Hi @joegallo, I've created a changelog YAML for you. |
It seems misleading to use IllegalArgumentException for the general case of "something, anything, went wrong here".

LGTM. As we've discussed offline I think we ought to broaden where we catch exceptions (since there are other places that would also result in the client never being notified). But this is definitely the most urgent and lowest risk place (since we have seen an exception right here in production).
The first catch block converts to an IllegalArgumentException which maps to a 400. The second block converts to a RuntimeException which maps to a 500. For bwc reasons, we don't want to change the first block, but at the same time it's not right to return a 400 for the second situation -- we don't know what happened and can't say for sure it's a problem with the request.

Related to #91977
Regardless of what exception is thrown while generating source from an
IngestDocument, we want to catch and handle the exception -- the contract forsource(..., true)is that it can throw anIllegalArgumentExceptionif there are self references, but now that we've seen other things go wrong inside the guts of that method (and given how hard they have been to diagnose!) I think a widercatchis justified (and remains justified even in a world where #91977 has been fixed).
