### Description

When running the AMS migration tool, the status message says: “Migration progress: GetStreamingPathsAndContentKeys finished. 440 jobs finished, 6 failed (out of 449)”.  
Response from endpoint [https://api.bitmovin.com/v1/streams/azure-media-services-migration/status?subscriptionId=MY\_SUBSCRIPTION\_ID](https://api.bitmovin.com/v1/streams/azure-media-services-migration/status?subscriptionId=MY_SUBSCRIPTION_ID) (GET) returns error 500.  
Response data: {“name”:“TypeError”,“message”:“null is not an object (evaluating ‘item.data’)”}  
The migration process gets stuck.

### Expected behavior

Migration should proceed to the next step. It would be nice to show the reason why some jobs failed.

### Reproduction steps

I’m just trying to use the migration tool as described in the documentation.
