Recently switched to Gemini 2.5 Flash (free tier). Getting this error:

Error: Stream cancelled; RPC from prefill servable to decode servable failed; Failed to close the streaming context; status = CANCELLED: Stream cancelled; RPC from prefill servable to decode servable failed [type.googleapis.com/util.ErrorSpacePayload=‘RPC::CANCELLED’]

The issue started happening only after switching to Gemini 2.5 flash (from 2.0 flash). Has anyone else seen this? Any known workarounds?

I’m getting error which sounds partially similar:
