Viliam Durina updated CALCITE-4785:
-----------------------------------
    Description: 
The following expression parses succesfully:

{{JSON_VALUE('bad-json', '$' DEFAULT 1 ON ERROR DEFAULT 2 ON ERROR)}}

The 2nd ON ERROR clause overrides the 1st one and the expression returns {{2}}. 
Instead, an error should be thrown.

> The parser allows multiple ON ERROR or ON EMPTY clauses for JSON_QUERY and 
> JSON_VALUE
