Unable to run a gradle github workflow

Question

I am trying to set up a workflow for my project. I used the standard "Configure with gradle" workflow, and just edited the java version from 11 to 17.

But when I push my code, it throws an error:

this is my workflow so far

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.
# This workflow will build a Java project with Gradle and cache/restore any dependencies to improve the workflow execution time
# For more information see: https://help.github.com/actions/language-and-framework-guides/building-and-testing-java-with-gradle

  Gradle User Home cache not found. Will initialize empty.
Error: Error: Gradle script '/home/runner/work/Slapbot-stewie/Slapbot-stewie/gradlew' is not executable.

I do not know how to fix this error, I found no relevant google search that can help with this.
