URL: https://github.com/apache/beam/issues/28131
### What happened?
I'm trying to send custom metrics to datadog using a DoFn but the python sdk
test harness is failing with an error that I don't know how to interpret:
```
Traceback (most recent call last):
File
"/usr/local/lib/python3.9/site-packages/apache_beam/runners/worker/sdk_worker_main.py",
line 181, in main
sdk_harness.run()
File
"/usr/local/lib/python3.9/site-packages/apache_beam/runners/worker/sdk_worker.py",
line 256, in run
getattr(self, SdkHarness.REQUEST_METHOD_PREFIX + request_type)(
TypeError: can only concatenate str (not "NoneType") to str
```
I'm running the streaming pipeline as a flex template in gcp dataflow, using
the python requests module for POST calls
