note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
-
I'll add the full backtrace to the first comment, to not pollute this bug report.
-
Would you like to work on a fix? [y/n]
No, I do not have the technical capabilities to work on a fix. But if someone wants to mentor me through it, and be patient while I learn Rust along the way, I'm happy to oblige.
To Reproduce
Steps to reproduce the behavior:
- Install Rexit via cargo | Build Rexit from the Main branch (I tried both)
- Run
rexit messages -t - Paste proper, working Authorization header, not including the word "Bearer".
- ...
- Profit
I am able to reproduce the bug in the main branch, too. That's the backtrace that I'll add to the first comment.
Environment

Hey, long time listener, first time caller. I have zero experience with Rust, and I usually use MacOS. But I was experiencing a similar issue, and I fixed it.
The gottcha for me was this: it turns out, (in powershell at least) if you try to use Ctrl-V to paste into stdin, the only input will be V rather than the clipboard contents. Rexit still says 'Login Successful', but that's not actually an indicator of success.
I used cURL with the bearer token, and to my surprise, got a valid response. So I ended up building it from source and hardcoding the token (even though I figured out later in powershell I could just right click). And everything worked!
I would suggest using cURL or whatever to check the token is valid. Good luck, I hope this helps.
So getting the logs would really help, you can also send me a message to my protonmail on my profile. The token is really long, have you tried waiting 10-15secs after pasting before pressing enter. Its wierd but might work
Same issue here. I checked out v2.0.2 and built from source.

Which token are you using to login, as there are two different ones. One for Reddit itself and one for Reddit chat (matrix.redditspace.com)
The gottcha for me was this: it turns out, (in powershell at least) if you try to use
Ctrl-Vto paste into stdin, the only input will beVrather than the clipboard contents.Rexitstill says 'Login Successful', but that's not actually an indicator of success.
This was it for me. Use right-click rather than Ctrl+V. Thanks for the tool!
