Hi everbody.
I think nobody faced that issue cause they integrated meilisearch to their app on production successfully. But me...
I have put master key on production(on hatchbox env area and ubuntu meili enviroment side), set enviroment to production.
Then meilisearch started successfuly with master key. It is givin same error when i tried search on app that was working clearly on development. "MeiliSearch::ApiError (403 Forbidden - The provided API key is invalid.. See https://docs.meilisearch.com/errors#invalid_api_key" There is tutorials on gorails about meilisearch but not on production. I researched that issue on web and meili docs but could not find any solution recommends... Can you share with me any sample setup or tutorial to fix it?
Thanks!
