Aino metadata not consistently extracting fields

Hi everyone,

I’m facing an issue with Aino metadata extraction and I’m not sure why it’s happening.

Sometimes the metadata returns all the expected fields, but other times it doesn’t return anything at all — not even a single value. The behavior is inconsistent, and I can’t find a pattern for when it works and when it fails.

What’s confusing is that I’m using the same document for testing. Earlier, this exact document returned all the correct field values, but now it suddenly stops extracting them. I haven’t changed the file, so I’m not sure what triggered this issue.

I’ve attached a screenshot of the metadata view for reference.

Has anyone experienced something similar or knows what might be causing this inconsistent behavior?

Any help or suggestions would be greatly appreciated.

Thanks!

  • Have you tried enabling logging in the Aino Metadata vault application and see if any errors get recorded? You can find the steps in the Aino administrator guide.

    If this is an on-premises vault, you can also check the Windows application log on the M-Files Server. Some errors, such as networking problems, may get recorded there.

    If you're still unable to resolve the issue, please reach out to M-Files Support for assistance.
