ASF GitHub Bot logged work on BEAM-6838: ---------------------------------------- Author: ASF GitHub Bot Created on: 21/Mar/19 00:16 Start Date: 21/Mar/19 00:16 Worklog Time Spent: 10m Work Description: youngoli commented on issue #8064: [BEAM-6838] Go SDK: Improving error msgs in pipeline serialization. URL: https://github.com/apache/beam/pull/8064#issuecomment-475076149 There definitely is a lot of repetition with the recursion, even before my changes. Though I'm not sure how to avoid that really. While it's a lot of information for users, it's important for debugging. Only alternative I can think of is adding some debug logs instead of some errors, so users can see the path being taken by examining logs. Here's a real-world example I've been using to test (I replaced the proto name though) > failed to encode custom coder: bad underlying type: bad element: bad field type: bad element: bad element: bad field type: bad element: bad field type: bad element: bad element: bad field type: bad field type: bad element: bad field type: unencodable type: protoapi.extensionMap And the new error: > Failed to encode custom coder for type protoapi.Message. Make sure the type was registered before calling beam.Init. For example: beam.RegisterType(reflect.TypeOf((*TypeName)(nil)).Elem()) > > Full error: failed to encode custom coder *my_package.MyProto[protoapi.Message], bad underlying type: failed to encode pointer *my_package.MyProto, bad base type: failed to encode struct my_package.MyProto, bad field type: failed to encode pointer *my_package.MyProto_MyField, bad base type: failed to encode struct my_package.MyProto_MyField, bad field type: unencodable type map[int32]protoapi.Message ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
