appimagetool.AppImage: Syntax error: word unexpected

[GaZaTu]

When using the armhf version of appimagetool in my armv7 run-on-arch-action (github actions) i get the following error:
/usr/bin/appimagetool.AppImage: 1: /usr/bin/appimagetool.AppImage: Syntax error: word unexpected (expecting ")").
Any idea why that could be happening?

ps: i did not get the same error on my x86_64 dev machine (i did get other errors tho xd)

cmake:

add_custom_target(appimage_appimagetool
  COMMAND mkdir -p ${CMAKE_BINARY_DIR}/_AppDir
  COMMAND cp ${PROJECT_SOURCE_DIR}/res/${PROJECT_NAME_FULL}.png ${CMAKE_BINARY_DIR}/_AppDir/${PROJECT_NAME_FULL}.png
  COMMAND make install DESTDIR=${CMAKE_BINARY_DIR}/_AppDir
  COMMAND appimagetool.AppImage -s deploy ${CMAKE_BINARY_DIR}/_AppDir/usr/share/applications/${PROJECT_NAME_FULL}.desktop
  COMMAND appimagetool.AppImage ${CMAKE_BINARY_DIR}/_AppDir
)

in case its relevant, i'm trying to package a Qt5 c++ app.
