# 53600: S3 URL for recording upload is invalid

Log Level: ERROR

## Description

The recording will not be processed.

Raised when the S3 URL specified in the recording's metadata is not valid.

### Possible causes

* If you have specified your own bucket, this is most likely due to the fact that the URL does not conform to an S3 URL.

### Possible solutions

* Set a valid S3 URL for uploading media or leave blank (media will be uploaded to the default bucket).
