I have changed the environment variable to be the SSH credentials to the jailbroken device and validated that the creds work but its not working with this tool. Am I doing something wrong?

Same issue on macos using Frida 16.1.4

I got it fixed by changing the SSH password to alpine. The environment variable SSH_PASSWORD doesn't seem to work. The error is related to the SCP protocol.

Thanks for figuring that out. Root cause seems to be that SSH_PASSWORD is only honored if SSH_USER is set too. https://github.com/ChiChou/bagbak/blob/0c8d6e1966f2777d43a390ecaf4702704407faec/index.js#L45

Yes, if you use custom password you need to specify SSH_USERNAME at the same time
