I'm encountering such error and I have no idea how to resolve this.
This exception is thrown when I attempts to delete a version or when I attempt to query a feature layer.
popular error over the last number of years,
for example https://community.esri.com/message/604893#comment-604893
but one suggestion on another thread said it went away when they shut down arcmap, rebooted and started over
other than that tidbit and the one in the link, I can't find anything definitive
Hi Dan,
Thanks for the response. I did all of that even to recreate my sde database , but still the same.
Why me???
sorry, I can't help, I avoid network data sources as much as possible
Hi @MarkSamuels
I got this error this morning, and I feel it has something to do with either the length of the filepath or the characters in the filepath. The FGDB I was trying to use was buried very deep in the file system. When I copied the FGDB locally to a very simple filepath I did not get the error anymore.
HTH
