Gemini Flash 1.5 errors for prohibted content

[ragnarbull]

I am checking some of the error messages I'm receiving with gemini-1.5-flash. I have the model doing content moderation for search queries.

When I search for say "trafficking victims" it returns "Please provide the query to classify." I'm assuming the user input here is completely wiped by the model?

I am also getting issues with the stop reason being PROHIBITED_CONTENT. Some very ordinary searches are returning this which is very frustrating. This is possibly a blocker to using these models in production. 

Also searches in non-supported languages are returning PROHIBITED_CONTENT - is this expected behavior?

Same for me and I'm setting all safetySettings to BLOCK_NONE
