I'm using the DD4T function FindAndStoreBinary together with BinaryDistributionModule to intercept calls for image files and retrieve them from the broker DB and physical location on the server. The problem I am encountering is that it only loads half of the images on the page. Also which images it loads seems to be random. In total the page only contains 8 images.

From the dd4t logs I pulled this error:

    WARN  2022-09-15 17:08:38,569  2390ms DefaultLogger          TryFindBinary      - Caught unexpected exception while retrieving binary with url /devportal/nl/Media/apis-consent_tcm112-158431.png (requested url: /devportal/nl/Media/apis-consent_tcm112-158431.png.

Could the token be expiring before all requests are handled? Are there other ways to find the cause of this issue?
