Welcome to the Microsoft Q&A and thank you for posting your questions here
It looks like you’re encountering a common issue in Azure Data Factory where the error message “Object reference not set to an instance of an object” can be tricky to diagnose. Here are a few steps you can take to troubleshoot and resolve this issue:
- Check Configuration: Ensure that all configurations and parameters for the activity are correctly set. Sometimes, a missing or incorrect configuration can cause this error.
- Review Dependencies: Verify that all dependencies and linked services are properly configured and accessible.
- Recreate Activity: Try deleting and recreating the “Get Metadata” activity in your pipeline. This can sometimes resolve issues caused by corrupted activity configurations.
- Integration Runtime: Ensure that your integration runtime is properly configured and running. Issues with the integration runtime can sometimes cause this error.
Regarding the log display issue,
the error message in your screenshot suggests that logs may not be immediately available for fresh activity executions. Ensure that the RunID is older than 2 days before attempting to view the logs.
If the issue persists beyond this period, it might be worth checking if there are any service disruptions
do let us know if issue persists. we will further investigate and help you out .
