The recommendation API fetches the language pairs from CX Server in order to validate source and target language of translation recommendation requests. This often fails and lead to log spam as well as failing recommendation requests.
There is some error handling in place so that validation is simply skipped when the language pairs are not available but it is not checking for the right exception type.

Error handling code for rec-api usage of CX /list/languagepairs/ that was fixed in this task was eventually removed in favor of using sitematrix data. Nothing to test here.
