Components: runner-core
Reporter: Mark Liu
Assignee: Robert Bradshaw
This comes from a Python 3 incompatible bug and mentioned in
https://github.com/apache/beam/pull/7521/files#r248993766. The fix decode
payload unconditionally in Python 2 or 3 but suggested by [~robertwb]:
"the Dataflow runner harness was fixed to always use proper coder URNs rather
than stuffing json-ized dataflow v1b3 cloud proto representations into the
payload".
