This is the output of the bash. I have no idea what causes this. My network has 3 organizations with 2 peers each and one orderer. And I have edited the fabic-node.yaml file to match the requirements.
IF anyone has any suggestions on what to do im all ears. Thank you

Basically, error code 4 is when you try to initialize connection with blockchain (SUT) but failed, error code 5 is when you fail to install smart contract and error code 6 is for other errors (e.g configuration)
