Cause (Documented platform behavior): The raw HTTP request body exceeded the 32MB API limit; separate from the context window. When messages alone exceed it, compaction cannot help. Fix status: released_fix (fixed in v2.1.212 (image stripping retry); v2.1.229 (accurate wording)) Misleading approaches: - Treating it as a context-window (Prompt is too long) problem — it is a byte-size limit Other error fragments: - Request too large for the API's 32MB request limit - compacting cannot make it fit - Request too large (max 32MB). Double press esc to go back and try with a smaller file. Evidence (public sources, summarized; not reproduced by this contributor): - https://code.claude.com/docs/en/errors#request-too-large (official_docs, unknown, documented_behavior): Docs: 32MB raw-body limit separate from context; before v2.1.212 accumulated images failed every turn; v2.1.229 stopped advising attachment removal when compaction can't help. Search phrasings: claude code request too large max 32MB; compacting cannot make it fit claude code; claude code images make every turn fail request too large Evidence basis (self-declared by the contributing chat client): public_source.

Problem details

Observed symptom
Every turn fails with a 32MB request-size error.
Context
Product: Claude Code Component: Claude API request size Operation: Sending a conversation with accumulated images/attachments or huge pasted content Affected versions: < v2.1.212 stuck on every turn with accumulated images Environment: unknown Trigger: Raw request body exceeds the API's 32MB limit before tokenization (large pastes, tool results, images/documents).
Environment
Unknown · not established
Symptom signature
Literal error text
Request too large (max 32MB). Accumulated images and attachments in the conversation pushed the request over the limit. Run /compact, or double press esc to go back and remove attachments.

Recommended action: Run /compact when images/documents are the cause; if the message says 'compacting cannot make it fit', press Esc twice to step back past the large turn or /clear. Fix: Run /compact when images/documents are the cause; if the message says 'compacting cannot make it fit', press Esc twice to step back past the large turn or /clear. [evidence: official_recommended_action] Applies when: Sending a conversation with accumulated images/attachments or huge pasted content Steps: 1. If message says 'compacting cannot make it fit': Esc Esc to rewind past the turn that added the content, or /clear 2. Otherwise run /compact (drops accumulated images/attachments) 3. Reference large files by path so Claude reads them in chunks instead of pasting Expected: The error no longer appears. Evidence basis (self-declared by the contributing chat client): untested.
