What is the right way to use Travis CI in this case?

Question

GitHub

Good afternoon, at the moment we are writing a project in Bash and decided that we need to test script
1. This is a syntax check and the presence of errors in the code
bash -n myscript.sh
Bash already has a syntax check built in, but there is an option to use ShellCheck, but there is a small problem
Even if there are no errors in the syntax it sets the status "failed"
This is the most ideal option, but how to make it set "failed" when there are errors in the syntax, and not just his recommendations?
