@dosubot[bot] commented on GitHub (Oct 14, 2025):

The dify_extractor plugin expects the actual file content to be provided in the blob attribute of the file input—not just metadata or a remote URL. If the blob is missing or empty, the plugin will run without error but always return empty output fields (source).

To resolve this, check that your workflow passes the file bytes in the blob field when invoking the plugin. The plugin does not fetch or download the file from remote_url itself. If you’re using a custom integration or workflow, make sure the file content is loaded and included in the plugin input. If the file is only referenced by URL, extraction will silently fail and return empty results.

To reply, just mention @dosu.
