When does this happen?

IF 413 HTTP error when uploading dataset items with files exceeding 1MB as raw bytes.

How others solved it

THEN Increase the `LANGFUSE_MAX_EVENT_SIZE_BYTES` and `LANGFUSE_MAX_BATCH_SIZE_BYTES` environment variables in your self-hosted deployment configuration (e.g., docker-compose.yml or Kubernetes Helm values) to accommodate larger payloads. Restart services after setting.

# In docker-compose.yml under the langfuse service environment section:
environment:
  - LANGFUSE_MAX_EVENT_SIZE_BYTES=5242880  # 5 MB
  - LANGFUSE_MAX_BATCH_SIZE_BYTES=10485760  # 10 MB
