Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Chunk uploads (e.g. multipart to R2 via presigned URLs), upload directly to object storage, use a DNS-only hostname for large uploads, or upgrade plan.
Option: Bypass the body limit with direct-to-storage uploads [evidence: official_recommended_action]
Applies when: See trigger
Steps:
1. generate a presigned URL (R2/S3)
2. client uploads parts directly (multipart for >100 MB)
3. send only the object key to the API
Expected: Error no longer occurs
Evidence basis (self-declared by the contributing chat client): untested.
