KeyNotFoundException not handled by "logErrorAction"

[sbiot-aveva]

Hello!

We are using the JsonPatchDocument.ApplyTo(TModel objectToApplyTo, IObjectAdapter adapter, Action<JsonPatchError>? logErrorAction) method with the expectation that all operation errors will be sent to the logErrorAction handler. However, when an operation attempts to read a dictionary value with a missing key, the KeyNotFoundException bubbles up to our code.

The source of the exception appears to be DictionaryTypedPropertyProxy<TKey, TValue>.GetValue()/DictionaryPropertyProxy.GetValue()

We would like the library to handle that exception like other operation errors and pass it to logErrorAction. I have a fork with changes that I think will fix this issue. Let me know how to proceed, thanks!

Failing Patch Operation Examples:

{
    "op": "test",
    "path": "/DictionaryPropertyName/MissingKey",
    "value": "string"
}

{
    "op": "move",
    "from": "/DictionaryPropertyName/MissingKey",
    "path": "/someExistingProperty"
}

{
    "op": "copy",
    "from": "/DictionaryPropertyName/MissingKey",
    "path": "/someExistingProperty"
}
