Hello @Arun_radhakrishna,

I think this may be a good candidate to report through Mission Control (my.alteryx.com) to ensure Customer Support is aware and can provide insight into resolution. The case submission process will also search the Knowledge Base in case there is a known solution! Please let me know if you have any questions about this process.

This should probably be in the Designer channel vs the Server. What are you trying to pull from your Orchestrator? Are you connecting via basic auth/service account or external app/oauth? --- my line of questioning is kind of 'why are you stuck on Alteryx's tool when you can do this via the Orchestrator API?'

[Arun_radhakrishna]

We are trying to start an automated process from the Alteryx workflow. Authentication used is basic authentication with username and password. Tested directly with CURL and its working fine so no issue with user account permissions. 

Our aim is to use automation to perform some steps in SAP in our alteryx workflow, which is not possible currently via Alteryx. So we use UiPath addon\connector which alteryx is providing to achieve this

Yeah... I'd do this via UiPath API in the download tool. UiPath has changed their Process API a few times recently so I wouldn't be surprised if Alteryx's tool gave you the dreaded parameters cannot be null error. Having said that Automation Suite gives you some additional control over if you've implemented these changes. What version are you running? I'd recommend opening the swagger -> testing the process start n Orchestrator Swagger. copying the JSON payload for the swagger -> running locally in Alteryx. Make sure you fill in your x-folder/organization id and you know your process release key.

I'm not 100% sure what you can do in UiPath in SAP vs in Alteryx but if your team wants to go in this route --- they should.
