Serverless deploy fails - Error: Write EPIPE - serverless-framework

Question

I have used Serverless Framework previously but lately I am having an error I cannot resolve. Serverless Framework version 3.8.0. was installed using npm. Node version 17.7.1. Running on Linux(Manjaro)
Running sls deploy
✔ Service deployed to stack test-api-dev (0s)
But nothing actually changes on AWS, nothing is actually deployed.
Running sls deploy | echo outputs
Running "serverless" from node_modules
✖ Uncaught exception
/home/mascs/api/node_modules/serverless/scripts/serverless.js:49
throw error;
^

Node.js v17.7.1
Running as sudo doesn't change things, so it doesn't seem to be a permissions issue.
Here is the serverless.yml I am using. Can't see any syntax errors.

I am at a bit of a loss here, would appreciate if anyone has any ideas.
Have tried uninstalling and then reinstalling Serverless Framework also but it has made no difference.
