There has been an error with your export

Hi friends,

On my edx server I am trying to export a course , then I got those errors :

There has been an error with your export.

Your course could not be exported to XML. There is not enough information to identify the failed component. Inspect your course to identify any problematic components and try again. The raw error message is: All strings must be XML compatible: Unicode or ASCII, no NULL bytes or control characters

On the cms log file I get this logs :

What can be the problem on my site?

@Shukurlu, It seems like there is some video in your course without a transcript set.
Have you checked to see that all videos in your course have a transcript?
Do you have transcripts for languages other than English?

We’ve had this issue when there has been a change of storage location, so a transcript was uploaded and stored in one S3 bucket, but then when it came time to export the bucket was no longer available.

We also had the same issue. Source from server which doesnot have s3(import) to the destination set up with Minio. Error as below

@Antony_Suresh were you able to resolve the issue? I’m facing the same issue with following logs

TypeError: Unicode-objects must be encoded before hashing

It happens when I try to import my course from one server to another.
