Liquibase 4.25 liquibase.properties changeLogFile reading error undefined key(s) for 'tag' when using strict option

I am using a Liquibase 4.25 custom docker image with base image eclipse-temurin:17-jre-focal.

The contents of liquibase.properties file are the following:

classpath=/liquibase/changelog:/liquibase/lib
strict=true
referenceDriver=oracle.jdbc.driver.OracleDriver
changeLogFile=PAN.oracle.xml
liquibase.outputFileEncoding=UTF-8

I get the following error when I execute the liquibase tag command.

java.lang.IllegalArgumentException: Strict check failed due to undefined key(s) for 'tag' command in file exists at path /liquibase/changelog/liquibase.properties'
