# Objective
The error messages that appear when a value cannot be serialized or
deserialized via reflection could be slightly improved.
When one of these operations fails, some users are confused about how to
resolve the issue. I've spoken with a few who didn't know they could
register `ReflectSerialize` themselves. We should try to clarify this to
some degree in the error messages.
## Solution
Add some more detail to the error messages.
For example, replacing this:
```
Type 'core::ops::RangeInclusive<f32>' did not register ReflectSerialize
```
with this:
```
Type `core::ops::RangeInclusive<f32>` did not register the `ReflectSerialize` type data. For certain types, this may need to be registered manually using `register_type_data`
```
I also added a separate error message if the type was not registered in
the type registry at all:
```
Type `core::ops::RangeInclusive<f32>` is not registered in the type registry
```
## Testing
You can test locally by running:
```
cargo test --package bevy_reflect
```

## Changelog
- Added error message for missing type registration when serializing
reflect data
- Changed error message for missing `ReflectSerialize` registration when
serializing reflect data
- Changed error message for missing `ReflectDeserialize` registration
when deserializing reflect data
