Getting configuration errors when installing modular input on heavy forwarder.

[clorne]

Hello,

I am trying to install a modular input.
On a standalone Splunk, there is no problem, the setup dashboard shows up perfectly.

But on an heavy forwarder I get the following error on the graphical interface of Splunk:
Unable to initialize modular input "gmail_bigquery" defined inside the app "TA_AI_NR_1R93_gmail_HF": Introspecting scheme=gmail_bigquery: script running failed (exited with code 1).

And in the _internal index:

It seems that something is missing in the configuration but I do not find what it could be ....

Cheers

Finally,
I use the command to debug the modular input:
./splunk cmd splunkd print-modinput-config --debug gmail .

This gave an other error message (different from what was logged into the _internals.

And I could correct this new error and then solved the issue
