Dian Fu commented on FLINK-22953:
---------------------------------
[~awayne] It seems that this issue is very similar to this one:
https://www.mail-archive.com/[email protected]/msg42510.html
Could you confirm that? The reason is that json format doesn't support list
type. If this is the case, this issue will be addressed in FLINK-23033 and will
be available in the coming 1.13.2.
> Using Types.LIST(Types.STRING()) in datastream result in crash

> number of strings in list isn't fixed.
> After define Row type using Types.LIST(Types.STRING()), job will crash:
