# M0151

This error means that a object literal is missing some fields, maybe because of a typo.

Erroneous code examples:

```motoko
{ first_name = "Fred" } : { firstName : Text }
{ firstName = "Fred" } : { firstName : Text; lastName : Text }
```

If you encounter this error, you need to add the missing field name to the
object literal.

```motoko
{ firstName = "Fred" } : { firstName : Text }
{ firstName = "Fred"; lastName = "Flintstone" } : { firstName : Text; lastName : Text }
```
