Root Cause

After decompression, the message size exceeds the configured max receive message size, causing an internal error even though the compressed size was within limits.

generic

中文

解压缩后，消息大小超过了配置的最大接收消息大小，即使压缩后的大小在限制内，也会导致内部错误。

Workarounds

  1. 95% success Increase the client's max receive message size to accommodate the decompressed payload: `channel = grpc.insecure_channel(target, options=[('grpc.max_receive_message_length', 2 * 1024 * 1024)])` 
    Increase the client's max receive message size to accommodate the decompressed payload: `channel = grpc.insecure_channel(target, options=[('grpc.max_receive_message_length', 2 * 1024 * 1024)])`
  2. 85% success On the server side, reduce the uncompressed message size by splitting large responses or using streaming instead of unary calls.

中文步骤

  1. Increase the client's max receive message size to accommodate the decompressed payload: `channel = grpc.insecure_channel(target, options=[('grpc.max_receive_message_length', 2 * 1024 * 1024)])`
  2. On the server side, reduce the uncompressed message size by splitting large responses or using streaming instead of unary calls.
  3. If using gRPC-Web, ensure the proxy's max buffer size is also increased (e.g., Envoy's `max_request_body_size`).

Dead Ends

Common approaches that don't work:

  1. Increasing the client's max send message size to match the decompressed size. 90% fail

    The error is on the receiving side; max send size controls outgoing messages, not incoming decompressed messages.

  2. Disabling compression on the server side to avoid decompression entirely. 50% fail

    This may break clients that rely on compression for performance; it also doesn't address the root cause of the size limit.

  3. Setting the environment variable GRPC_MAX_RECEIVE_MESSAGE_LENGTH to a value lower than the compressed size. 95% fail

    This would reject the message before decompression, worsening the issue.
