No error given when wrong configuration of index chat subobject #5814
Description
Describe the bug
When using the chat completions feature, if the documentTemplate field of the chat sub-object in the index index is not valid, the chat completions won't work and won't let the user know why.
To Reproduce
Configure chat completions with correct:
- Index chat settings (description & documentTemplate)
- Chat workspace
Then use the chat completions feature and try to get the LLMs to retrieve documents.
Expected behavior
At least Meilisearch should return an error, ideally an error that the LLM can understand and pass it back to the human user.
Meilisearch version:
v1.16.0
