Youtube node doesn't work with BINARY_DATA_MODE filesystem in 2.0

Questions

I set BINARY_DATA_MODE to filesystem in preparation for version 2.0. Since then, the YouTube node no longer works for uploads because MIME Type:

video/mp4 is not being passed through, or rather, the YouTube node is seeing it as application/binary. Is this a bug?

What is the error message (if any)?

This is a known issue with the YouTube node when using BINARY_DATA_MODE=filesystem. The node isn’t properly handling the MIME type conversion from filesystem storage. As a temporary workaround, you can set BINARY_DATA_MODE back to ‘default’ or use the HTTP Request node to upload videos directly to YouTube’s API.

Would you mind sharing your workflow JSON so we can take a closer look at your specific setup? This will help investigate if there are any additional configuration issues.
