How to fix Splunk Add-on Builder error - RuntimeError: assist binary not found?

[apignata]

I am on a new install of Splunk 9.0.1 and add-on builder 4.1.1.
- creating a python script with check pointing as a Data Collection input.
- testing (with Test button) works as intended on the Edit Data Input
- after publishing I am not able to create a new input to start collecting events
- The script works as intended without the checkpoints
- Code of the check point below:

for service in r_json["response"]:
    state = helper.get_check_point(str(service["name"]) + str(service["appstack"]))
    if state is None:
        final_result.append(service)
        helper.save_check_point(str(service["name"]) + str(service["appstack"]), "Indexed")

    #helper.delete_check_point(str(service["name"]) + str(service["appstack"]))

- Index="_internal" error are below

I made suggested change to disable the data input but I am still getting the same error. 
I do not see permission to disable the whole app though. Can you please help as I am stuck !

I just upgraded my dev environment to Splunk Enterprise 9.1.0.1 and add-on builder 4.1.3 
And I cannot reproduce this error. What versions are You using?

I'm experience the same issue after deleting a data input.

Any solution?

I had same problem. I just disabled "Splunk Assist Supervisor" Data Inputs

There are two data inputs with same name, I disabled both, but the one in image should be enough.

Actually , i finally disabled whole splunk_assist app.
