payload has no content attribute in process_job method

[AissaGeek]

Description:

The code attempts to access job.get('payload', {}).get('content', {}).get('size'), but it seems that the main payload dictionary does not have a content key.

Example of a payload

As you may notice content dict is inside properties. This could lead to unexpected behavior or errors if the content key is expected to be present.

Proposed Solution

Consider checking the presence of content inside payload or inside properties
