webservice debug error -1967362033: OS and Network Services: (Hex 0x8ABC700F) Invalid argument(s).

[aartjan]

I have just made a few VI updates to a webservice in LV2020. I always run the webservice right from within the project to check the updates. All of a sudden I run into error Error -1967362033 when trying to run in debug mode. I have tried multiple things to find a solution, but unfortunately without a fix.

- I rebooted the PC

- I ran Labview in Admin mode

- I ran another webservice in debug mode without issues

- I ran the project on a newer Labview version

- I ran the project on another PC in a newer version

The error was consistent in all cases. Unfortunately, I can't find any detailed explanation online to debug this error.

There was an error running the web service on the debug server: Error -1967362033 occurred at NI Web Service Provider.lvlib:Elevated Copy.vi

Possible reason(s):

OS and Network Services: (Hex 0x8ABC700F) Invalid argument(s).

I moved this question to a support request and was advised to rebuild the webservice. I share this solution for future benefit for all.

While rebuilding the webservice, I found the cause of the error. Apparently, I had inadvertently stopped autopopulating the "public content" folder. This was the only cause of the error. It took me a long time to find.
It was not too hard to move the methods to a new webservice: the endpoint definitions remain intact when moving directly from one webservice to another.
