> --------------------------------------------------------------
>
> Key: FLINK-22953
> URL: https://issues.apache.org/jira/browse/FLINK-22953
> Project: Flink
> Issue Type: Bug
> Components: API / Python
> Affects Versions: 1.13.1
> Environment: python==3.7.5
> flink==1.13.1
> Reporter: awayne
> Priority: Critical
> Labels: stale-critical

> In our business, we need to deserialize JSON like this:
> {code:java}
> {
> ...,
> "texts": ["a", "b", "c"],
> ...
> }{code}
> number of strings in list isn't fixed.
> After define Row type using Types.LIST(Types.STRING()), job will crash:
> {code:java}
