Problem Loading App Unknown error.TypeLoadException

[SBK]

Hi all,

I have a model which converts and transforms an excel file to a different format. No interface or action tools are used, just local file inputs, and yet, when I deploy the WF to the gallery, it won't run and keeps throwing the UnknownError.Typeloadexception error.

Any idea what the root cause is or how I can troubleshoot it? I don't have any issue running other workflows, and this one also runs perfectly fine on my desktop. 

Thanks.

Hi @SBK ,

Without seeing your workflow it's difficult to know, but I would begin by checking your inputs are not pointing to local drives, such as the C drive on your PC as these will not be visible from the server.

Also, I would check that any connection to a data source is also set up on the server.

Thanks @mceleavey 

Not sure what the root cause on this one but I actually solved this by creating a brand new workflow with a simple input and select. I was able to successfully publish that one, so I gradually copied and pasted bits from my original workflow into, while constantly checking that I could still publish.

It makes little sense, I know, but that's how it worked for me, in case anyone else faces the same error.
