apiKeyis selected with nullish coalescing, so an emptyXQUIK_API_KEY(common when.envcontainsXQUIK_API_KEY=) wins over a populatedHERMES_TWEET_API_KEY. In that configuration,searchTweetsWithXquikreceives"", fails the trim check, and everysearch_tweetscall errors even though the alternate key is set as documented. Use a fallback that treats blank strings as missing (e.g., trim before choosing, or use a non-empty check) so the Hermes key path actually works.Useful? React with 👍 / 👎.
