Parameter not valid error

[rdeshpande]

Hello Community

Today I tried to open a workflow that I had worked on yesterday and I got "Parameter is not valid" error. See attached. Any suggestion to resolve this error? My other workflows seems to open fine. Now I am worried that one day this error will show on my other workflows also.

Any help is sincerely appreciated. Thank you in advance.

Hi! 
  If you updated Alteryx Designer, the new version may be causing compatibility issues. Try opening the workflow on a machine running a previous version of Alteryx Designer. And if this is your scenario, ensure that all tools and custom macros used in the workflow are installed.

Thanks Wesley for  your reply.

I did update the workflow in new version and saved it. Also it is not using any new features such as Controlled container. We did try to open the workflow in previous version and we got the same error.

Thanks again for your help.

Of course, @rdeshpande.

Do you have some backup of your previous workflow? I would recommend to see what updates you changed. 

"We did try to open the workflow in previous version and we got the same error." Do you mean previous version of Alteryx or previous version of your workflow?

Sorry I meant previous version of Alteryx.

The previous version of workflow is completely different. I made significant changes in this version of workflow.

Thanks much for helping
