Ben Sidhom created BEAM-3793:
--------------------------------
Summary: SDK harness should log bad gRPC responses
Key: BEAM-3793
URL: https://issues.apache.org/jira/browse/BEAM-3793
Project: Beam
Issue Type: Bug
Components: sdk-go
Reporter: Ben Sidhom
Assignee: Henning Rohde
As of now, if a null ProvisionInfo is passed to the boot code, it panics when
trying to convert to JSON. It should at the very least log a useful error
message if a bad ProvisionInfo is received.
Sample stack trace:
panic: reflect: call of reflect.Value.Field on zero Value
goroutine 1 [running]:
reflect.Value.Field(0x0, 0x0, 0x0, 0x0, 0x0, 0x1, 0x81f2e0)
