Error when using xonsh as default shell

[aspieln3r]

I have my default shell set to xonsh
Even thought the sysz has #!/usr/bin/env bash, it is somehow invoking $SHELL and I'm getting a traceback error when I press ? to get keybindings. Error goes away when I run sysz with env SHELL=/usr/bin/bash sysz from xonsh. I'm attaching screenshot of traceback from xonsh and you can see its trying to run something from sysz and getting syntax error.

(Screenshot because I cannot copy from sysz window)

I updated to 1.4.1 but issue is still present 😬

reverting current fix and setting SHELL=/bin/bash on top of the script works.

reading junegunn/fzf#2627 (comment) , fzf is not going to change current behavior.

Also from junegunn/fzf#481 (comment) , the recommended way to force a shell is to override SHELL from the script
