@rehan243 commented on GitHub (May 4, 2026):

Ran into this "API Error: Content block not found" issue with kimi-k2.6:cloud too, turns out it's related to how the model handles file reads. We hit this at Reallytics.ai when processing large codebases - our RAG pipeline was throwing similar errors when it encountered certain file types. Not gonna lie, took us a few tries to debug, but it ended up being an issue with the model's context window config. Specifically, the max_tokens param was set too low, causing it to truncate the content. We've since bumped that up to 4096 and it's been smooth sailing. The logs you posted show it's reading multiple files, so maybe that's the issue here? We've seen this exact error with ollama v0.3.x, so if you're on that version, might wanna check your model config.
