Liquibase looks for a strange path, when loading data from csv and throws an error

Liquibase version: 4.7

The path that liquibase is looking for is a combination between the changeset path and the csv content.

Error message

Caused by: liquibase.exception.MigrationFailedException: Migration failed for change set config/liquibase/changelog/v2_1_data_update.xml::20210206-1_local::beng:
     Reason: java.nio.file.InvalidPathException: Illegal char <"> at index 30: config/liquibase/changelog\[{ "attId": 0, "refSystem": "MOXIS",

Change set for loading the data, that is failing:

 <changeSet id="20210206-1_local" author="beng" context="dev" dbms="h2">
        <comment>load moxis documents test data for internal users 21-30</comment>
