Migration not working with Grails 6 on Tomcat 9

[Lastone17]

Steps to Reproduce

1. build war (grails war)
2. try to deploy war on tomcat

Actual Behaviour

I am aware of the issue with the plugin, so I added:
implementation ('org.grails.plugins:database-migration:4.2.1') { exclude module: 'spring-boot-cli' }
implementation 'org.liquibase:liquibase-core:4.19.0'

Also using this liquibase-core. If i run it locally in intellij everything is fine but on Tomcat i get:
liquibase.exception.ChangeLogParseException: liquibase.exception.SetupException: Non-existent directory: C:\Program%20Files\Tomcat\apache-tomcat-9.0.86\webapps\<appname>\WEB-INF\classes

Environment Information

• Operating System: Windows
• Tomcat: 9.0.86
• liquibase: 4.19.0
• Grails Version: 6.1.2
• Plugin Version: 4.2.1
• Database: mysql
• JDK Version: 11

I am having a very similar issue. I get the following error when I try to run the war. I get the same error if I put in an erroneous filename for updateOnStartFileName. I am completely stuck please help!
