# Troubleshooting With any troubleshooting, the first three things to try are: 1. Check the plugin's Log entries. If the normal operations of the plugin are not creating informative log entries, you can temporarily turn on Debug mode (this can create a lot of entries). 2. Check the plugin's Mapping Errors tab. There is [some documentation about this tab](./mapping-errors.md). 3. Check your PHP error logs. If you don't know how to access these, talk to your web host. ## Enabling Plugin logs If you are new to the plugin, make sure you've enabled logs: - Use the Log Settings screen to configure how to handle log entries. Once enabled, they are added to a custom post type called Logs in the WordPress menu. - If the plugin tries to create or update data, or to make an API call to Salesforce, but WordPress or Salesforce encounter errors, the plugin will always try to create a log entry. If you see entries, review both the title and content of each. ## Connection and authorization issues ### Missing Authorize tab If you load the plugin's Settings screen and you do not see an Authorize tab, this means there are required fields missing from your Settings tab. You must have accurate values for these fields: - Consumer Key - Consumer Secret - Callback URL - Login Base URL - Authorize URL Path - Token URL Path ### Error: invalid_client_id It can take a few minutes for a new app to be fully set up in Salesforce. If you get a `error=invalid_client_id&error_description=client%20identifier%20invalid` URL when you try to authorize with WordPress during the installation, wait a few minutes and then try again. This error can also happen if the Salesforce Consumer Key is entered incorrectly in the plugin settings. ### Error: redirect_uri_mismatch This error usually means the Callback URL in the plugin settings does not match the Callback URL for the app in Salesforce. Typically, the URL is something like this: https://yoursite/wp-admin/options-general.php?page=object-sync-salesforce-admin&tab=authorize. ### Error(0) This error comes from Salesforce but the plugin is not able to detect it before the page loads. Usually it comes from one of these things: 1. The connection is down 2. The SSL is incorrect 3. The login base URL is incorrect ### Error: 400 Sometimes Salesforce returns an unhelpful 400 error (perhaps with a `grant type not supported` message). 400 errors from Salesforce mean that the request couldn't be understood. This can happen if the Login base URL setting is using your instance name (ex https://clientname.lightning.force.com) rather than the more generic https://test.salesforce.com for sandboxes and https://login.salesforce.com for production instances. Salesforce will handle redirecting the plugin to the proper instance; you should always be able to use the generic URLs. ### Error: 401 Sometimes Salesforce returns a 401 error. This means the session ID or OAuth token has expired. This can mean that you've already tried to authorize, but it failed, or that too much time has passed. Try to disconnect and reconnect the plugin. Also, make sure your Salesforce app has the proper permissions: "Manage user data via APIs (api)" and "Perform requests on your behalf at any time (refresh_token, offline_access)". ### Plugin redirects after logging in, but does not finish activating If the plugin allows you to authorize in Salesforce, but does not finish activating in WordPress, consider these possible issues: 1. Insufficient app permissions in Salesforce. Make sure the app's permissions are at least "Perform requests on your behalf at any time" for OAuth Scope as well as the appropriate other scopes for your application. Many setups will also need to select "Manage user data via APIs (api)" as one of these scopes. If you change permissions, give Salesforce a few minutes before trying to connect again. 2. The plugin may have been unable to create its required database tables. If you think this may be the case, refer to [this document](./troubleshooting-unable-to-create-database-tables.md) for the necessary SQL. 3. Mismatched settings between the plugin and the expected values in Salesforce. ## Fieldmap issues If you are successfully authenticated with Salesforce, but you have a fieldmap that is not passing data, there are several ways to troubleshoot. Always check your PHP error logs first. ### Fieldmaps cannot be created There appear to be some server configurations that have trouble creating the required database tables for this plugin to run. If you are unable to create fieldmaps, check to see if the `wp_object_sync_sf_field_map` table exists. If this table does not exist, and you have access to create database tables directly, refer to [this document](./troubleshooting-unable-to-create-database-tables.md) for the correct SQL to create them. ### There are no Salesforce objects in the fieldmap dropdown When there are no values in the list of Salesforce objects, this means the plugin can’t access any of the objects in your Salesforce. There are three likely causes for this: 1. You need to change the OAuth scope on the app you created in Salesforce. For most uses with this plugin, you’ll want to use "Perform requests on your behalf at any time" and "Manage user data via APIs (api)" If you do change these, you’ll need to wait several minutes before trying again, as Salesforce is rather slow on this. 2. Your Salesforce objects might not be accessible to the Salesforce user who has authenticated with WordPress via this plugin. 3. The Salesforce objects might have other restrictive permissions. ## Object map issues and sync issues If you are successfully authenticated with Salesforce, but you are unable to create or update an object map between two records, there are several ways to troubleshoot. Remember to check the plugin logs, the [mapping errors tab](./mapping-errors.md), and/or your server's PHP error logs first. ### Sync error troubleshooting There are some steps (in addition to logs) that you can take regardless of which direction is having issues: - Clear the plugin cache on the Fieldmaps screen. - Install the [WP Crontrol](https://wordpress.org/plugins/wp-crontrol/) plugin to inspect your site's cron jobs. Make sure the `action_scheduler_run_queue` job is running. - Check the plugin's Scheduling screen to make sure your schedule is configured correctly. - Check Action Scheduler's Scheduled Actions screen at wp-admin/tools.php?page=action-scheduler and make sure it is running the plugin's actions as it should. ### Troubleshooting for pushing data to Salesforce When pushing data from WordPress to Salesforce, the plugin provides two modes: synchronous and asynchronous. Asynchronous tasks rely on the plugin's queue system, which itself (by default) relies on the WordPress cron system. When you encounter problems pushing data to Salesforce, it can be helpful to try both modes to see if one of them is causing the issues. See the [fieldmap documentation](./mapping.md#createedit-a-fieldmap) for further detail about these modes and how to switch between them. ### Troubleshooting for pulling data from Salesforce When pulling data from Salesforce to WordPress, the plugin relies exclusively on the plugin's queue system, which itself (by default) relies on the WordPress cron system. This means that if these systems are not working correctly, data will not be pulled into Salesforce. To start this kind of troubleshooting, a few steps may be helpful: 1. If you haven't already done so, turn on the plugin's Debug Mode. 2. Watch the Logs screen to make sure that the plugin is creating entries based on your schedule settings. For example, if the plugin is supposed to look for new Contact data changes every five minutes, make sure that this is actually happening. 3. In Debug Mode, the plugin will create log entries for every query that it sends to the Salesforce API. If they are running at the correct schedule (see above), also make sure that these queries are querying the correct data in Salesforce. 4. Look for any error logs or useful debug messages from these queries.
