Description
Sir,
I'm getting 400 badgateway error with my NodeJS function (NodeJS 16 runtime)
My OpenWhisk cluster is fine, deployed based on K8s, no errors occur.

Of course, I can also directly use the wsk command line to trigger my test function:

This seems like everything is working fine, however I am unable to access my function via HTTP request, I have created the relevant POST request API and have HTTP access via the configured 31005 port:


Therefore, I would like to ask how to adjust my system so that the following HTTP access errors will not occur.

My research team and I have encountered this obvious problem and would like to ask some experts for advice.
