Error while parsing a JSON_TABLE statement with placeholders in it

[priyanshi-yb]

If there is a select statement having JSON_TABLE syntax with placeholders in place of constant data -

SELECT jt.* FROM
 my_films,
 JSON_TABLE (js, $1
   PASSING $2 AS filter, $3 AS filter2
     COLUMNS (
     id FOR ORDINALITY,
     kind text PATH '$.kind',
     title text FORMAT JSON PATH '$.films[*].title' OMIT QUOTES,
     director text PATH '$.films[*].director' KEEP QUOTES)) AS jt

this is the error comes while parsing this query using the Parse() function -

ERROR:  only string constants are supported in JSON_TABLE path specification

Is this a bug or an expected failure?
Do you think there's any workaround to be able to parse this statement?
