Jark Wu commented on FLINK-22968:
---------------------------------
But I have to admit we should improve the exception message a bit. Will change
the title and description.

> Key: FLINK-22968
> URL: https://issues.apache.org/jira/browse/FLINK-22968
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / API
> Affects Versions: 1.12.3, 1.13.1
> Environment: {color:#FF0000}*Flink-1.13.1 and Flink-1.12.1*{color}
> Reporter: DaChun
> Priority: Blocker
> Attachments: test.scala, this_error.txt
>
>
> When I run the program, the error is as follows:
> The specific error is in this_ error.txt,
> But the error prompts me to write an issue
> Caused by: org.apache.flink.api.common.InvalidProgramException: Table program
> cannot be compiled. This is a bug. Please file an issue.
> It's very easy to read a stream and convert it into a table mode. The generic
> type is string
> Then an error is reported. The code is in test. Scala and the error is in
> this_ error.txt
> But I try to create an entity class by myself, and then assign generics to
> this entity class, and then I can pass it normally,
> Or with row type, do you have to create your own entity class, not with
> string type?
