op signin not working with here document (EOF)

TimonvHardeveld · November 2020

First of all, I love the 1password cli and it encouraged me start developing my shell skills.

I've been trying to get op to work with my git-credential helper. I noticed that it worked if I was already logged in and used the --session token. But if my session is expired, the script returns a 401 error;
[ERROR] 2020/11/30 10:29:28 Authentication: DB: 401: Unauthorized

I've traced it back to the input of a multiline to the command.

Let's say I have the file git-credential-op with the following code;

#!/bin/bash
eval $(op signin [accountname] --session="[SessionVariable]")

When I call it like this:
git-credential-op get username=[accountname]
It works fine and asks for the password.

When I call it like this, to imitate how the credential-helper is called to my understanding;

git-credential-op get <<EOF
host=[hostname]
username=[accountname]
EOF

I get the 401 error.

Am I doing something really wrong here, or is this a bug with op?
The only workaround I now have is to make sure I'm logged in already before calling any git commands, but that's not really long-term viable.

Thanks in advance

Hello, thanks for writing in with your question!

We don't really provide shell scripting advice or tutorials (lots of those already exist on the internet!), but let me see if I can give you a nudge in the right direction. It looks to be an issue with your git-credential-op script, rather than a bug in op. A heredoc would get passed to your git-credential-op as content in STDIN. Your script isn't reading anything from STDIN. It would need to do so and then pass the content of STDIN to op.

I hope that that's enough for you to build off of. I'm excited to see what you put together.
