$index['host'] variable not existing : throwing error on installatin

Host should get automatically set from the describeIndex api call to pinecone. Needs more info I think

Just here to confirm this error persist in later installs.

(it also prevents me from saving the search api index since the select field is empty)

Can you provide more info? Maybe the UI needs to be made more clear that you do the configuration in Pinecone and just select the one you created within Drupal
