Alteryx Gallery: Object not set to an instance of an object: Sharepoint Output Tool

[Paras_G]

I am trying to write a simple data to the sharepoint list, the workflow just has an input tool, Select and Sharepoint Output tool. I am not able to understand the reason why gallery is throwing the error. "Object not set to an instance of an object"

Things to consider:

1. Runs fine on designer whatsoever but fails on gallery all the time.

2. Gallery and designer are on same version.

3. No special columns in the sharepoint list.

4. No nulls in data.

5. Using the Sharepoint online and App only authentication credentials. 

It looks like a gallery issue. Has anyone experienced this before or can help to troubleshoot this

hi @Paras_G 

Can you check the TLS settings on the server?

If you are the admin trying enabling the different TLS protocols on the server and test it. 

Thanks
