I’m using the Twitter API v2 in Postman and I’m getting the following error in the console whenever I send a request:

“Missing required env variable:” “consumer\_key”  
I checked the collection variables and the consumer\_key is set, but I’m still getting this error.

Try posting a screenshot of your collection environment variables, the request, response, the console log, and anything else that might be pertinent.
