Hi, I'm following the tutorial to run the "flink-playground/table-walkthrough" project on IDEA. However, I got *the exception as follows:*
Exception in thread "main" org.apache.flink.table.api.ValidationException: Unable to create a source for reading table 'default_catalog.default_database.transactions'. *The key localhost environment info shows below:* 1.
