PyQt Not building please help

I am trying to build an AppImage for my PyQt app.
It requires Python 3
And Qt 5

I have put together a bash script to do the whole build process.
I’m concerned as the Conda plugin I am using seems to create files with hard-coded absolute paths, I have tried specifying paths that might work in my bootstrap file (which you can see in the build script below) file, with no luck
Am I missing something, or should I ask this elsewhere?

when I run it I see:

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Reinstalling the application may fix this problem.
/tmp/.mount_Blue_LjwovJA/AppRun: line 14:  2448 Aborted                 (core dumped) "$RUN_DIR/usr/conda/bin/python" "$RUN_DIR/usr/opt/blue-log-viewer/blue-log-viewer.py" $@

Here is my build script (the lines around the text “# get actual directory:” run inside the AppImage)

#!/usr/bin/env bash

# Stop on first error
set -e
