ODK Validate Errors:

When I upload my tool to odk validator I get the following error : Something broke the parser.
java.lang.ClassCastException: class java.lang.Double cannot be cast to class java.lang.String (java.lang.Double and java.lang.String are in module java.base of loader ‘bootstrap’)

The following files failed validation:
