I am not familiar with this particular table or data connector. It is not uncommon for columns or rows to be empty in tables.

Could it be that these entries do not contain error codes?

Maybe try "summarize count() by ErrorCode" to see if codes are common.

I guess I wouldn't look at this and see an issue normally. You might consider opening a support case otherwise. This appears to be a diagnostic log so there isn't more you can do on your end.

The specific issue is that when an error is raised by ADF in a Debug Session (Sandbox), the error details that are reported by Azure Data Factory are inaccessible within Log Analytics.

This question was posted by the MSFT engineer that responded to the support case I raised reporting this issue.

Thank you for your information. No, actually we can see the error message from ADF UI portal but are not able to see error message in Log Analytics ADF Sandbox table. Not just Error Message Column, but also the same for "Input, Output and Error Code" columns. This scenario is easy to repro.
