Volodymyr Tkach created DRILL-5939:
--------------------------------------
Summary: NullPointerException in convert_toJSON function
Key: DRILL-5939
URL: https://issues.apache.org/jira/browse/DRILL-5939
Project: Apache Drill
Issue Type: Bug
Reporter: Volodymyr Tkach
Priority: Minor
The query: `select convert_toJSON(convert_fromJSON('\{"key": "value"\}')) from
(values(1));` fails with exception.
Although, when we apply it for the data from the file from disk it succeeds.
select convert_toJSON(convert_fromJSON(columns\[0\])) from dfs.tmp.`some.csv`;
Some.csv
\{"key":"val"\},val2
{noformat}
