Hi @mferwerda1111​ could you provide your full log file when this error has occured? I don't personally have experience with this error, but with the log file I can provide more information to someone more familiar. If this is an urgent matter, I would submit a support case with us so that we can help you directly. Happy to help :)

Hi Evie,

I think I am OK. We have a number of folks all using the same connection store file, and I think someone installed, or re-installed the sharepointonline connector, which seems to overwrite the provided WebSphere definition that comes with that transformer package, that I customized to our values. There does not seem to be a way to dupicate that webserivce defintion, or I am missing that somehow, renaming it seems to not make it work either. But I got it working again, by re-doing the web service definition with FME 2020 to our values.
