Case # - 00820342

I have opened a case but I thought I would pose this question to the forum as well. Curious if anyone knows the cause or remedy for the following error.

Error: value cannot be null. Parameter name: key

We are running the latest version of Veeam. The error occurred on a VM that has previously backed up successfully until just now.

Thanks.

Response from support: "Usually this is a one-time issue with the database when an attempt is made to pull data that isn't fulfilled. Have you seen the error since it appeared this time?"

Since this was the first time it occurred I will monitor and update if reoccurs. Otherwise, looks like it might just be a one time deal.

This server backed up successfully last night. So support's reply that the error may have been a one time occurrence seems to hold true at this point.
