Difference of shell execution between command mode and interactive mode

Question

The problem. I am doing shell script that running from the desktop launcher, and it failed to execute in certain condition. To express the problem, I very simplify the problem code. The code is very simple:

uxterm -e bash -c 'echo 1 | sudoedit /etc/fstab'

It works good when I run it from the terminal emulator, but when I make it launch from the desktop environment, it fails. Launch from the desktop I mean launching from sway WM with this config

bindsym Mod4+F10 exec uxterm -e bash -c 'echo 1 | sudoedit /etc/fstab'

I also tried alacritty terminal emulator, and weston compositor.

When I use uxterm -e bash path/to/script, it works good.

What is the difference between launching from the terminal and from the desktop, between -c option and launching script?

I expect smooth launch in any environment, and the most important, I need to know whats wrong here.

EDIT: To be clear, there is my actual script that works with the problem:

#!/bin/bash

ere-escape() { sed 's/[[^.$()|*+?{\]/\\&/g' ; } ; export -f ere-escape
bre-escape() { sed 's/[[*$\^.]/\\&/g'       ; } ; export -f bre-escape

filelist()
{
    source profile-dirs
    for LAYER in "${PROFILE_LAYERS[@]}"
    do
        find "$PROFILE_DIR/home/$LAYER" -type f -printf '%P\0'  2> /dev/null
        find "$PROFILE_DIR/root/$LAYER" -type f -printf '/%P\0' 2> /dev/null
    done | (
        if [ "$1" ]
            then cd -- "$HOME" && xargs -0 -- grep --null -il -F -e "$1" -- 2> /dev/null
            else cat
        fi
    ) | LC_COLLATE=C sort -z
}
export -f filelist

EDIT: More details discovered. Somehow, editor is not becoming a foreground process.

You can see that sudoedit stays as foreground process (stat Ss+).
