Drupal connector: Empty error message when no TMs are available for a given lang combination in our Lilt <> Drupal connector

[amiraLilt]

If you try to send a job to Lilt using TMGMT and Lilt as a provider and there is not matching TM for that language combination with the API key selected, the following error message is shown when trying to submit the job.

The error does not provide any information. Ideally, if no Lilt TMs are available for the language combination chosen in Drupal, job submission should not be allowed and if so, the error message should provide the end user with actionable information (e.g. there is no TM with that language combination in Lilt, please create one before you submit the job).
