The repository is private. The builds logs are not providing additional information unfortunately.

It looks like this error might be a user error. If this is the case, it might be good to wrap the imagemin() with a try/catch block and use utils.build.failBuild(). This method ensures that uncaught exceptions are reported as user errors instead of plugin bugs. More information can be found here.
