REST API Modular Input: After creating a custom search command as a Python script, why am I getting the following "parse transport header" error message?

[kiril123]

Hello,

I have created a custom search command in Splunk as a Python script. When I run the command in Splunk SPL, I get the following error message:

ERROR ChunkedExternProcessor - Failed attempting to parse transport header

Does anyone has any suggestions?

This is the output of commands.conf:

[sankey]
chunked = true
enableheader = false
filename = system_python.path
command.arg.1 = sankey.py

[jpass]

Did you ever figure this out? I'm having the same problem.
