Empty response body when increasing the max-token value

Has anyone experienced this or do you have any solutions?
When I increase the max-tokens, for example 250, the response body is empty (There is nothing even errors massages)
But it works fine for 150 max tokens.

Can you share an example query here? This seems like a bug.

This is an example query I tested and it shows an empty body:
“Donnez une dissertation de 1500 mots environ sur la destruction de l’environnement”

My max-token is set at 2000

Same bug here. Anyone has resolved it?
