Invalid Security Token *only* when using Transcribe

Question

I am using Vapor to deploy my laravel application to AWS. The keys that I am using locally to connect to AWS Transcribe are working, but I am getting this error when I send a request to Transcribe from one of my Vapor environments:

{"__type":"UnrecognizedClientException","message":"The security token included in the request is invalid."}

I am using my environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY to authenticate in multiple places (including my Transcribe request) but this is the only failure. Again, this works fine locally. I have also opened a ticket with Vapor so they may have a solution for me soon - but my gut tells me this needs to be solved from within my AWS console.

Any suggestions are appreciated! Thanks in advance.

Accepted Answer

Hello.

Are the access keys set on Vapor the same as when you verified it on your local PC?  
A common problem is that the access key and secret access key pair do not match.  
Also, will it result in an error if I write the access key directly in the code?
