JSON_VALID and any JSON function doesnt work correctly whe there is a double-quote char (escaped) inside a value in a complex json array (more tha 2 elements)

Still 10.3.17. any JSON function will return NULL when there is a quoted char in a complex JSON array. Witth a Json single element array there is no problem:

Tests:
Phrase: Venture "Extended" Edition

1. SELECT JSON_QUOTE('Venture "Extended" Edition');
   Returns: "Venture \"Extended\" Edition"
2. SELECT CONCAT('[ {"Year":1999,"Make":"Chevy","Model":', JSON_QUOTE('Venture \"Extended\" Edition'),'}

   ]') INTO @_json;
   SELECT JSON_VALID(@_json), JSON_LENGTH(@_json);
   Returns 1 and 1 (for a single element there is no problem)

3. SELECT '[ {"Year":1997,"Make":"Ford","Model":"E350","Description":"ac, abs, moon","Price":3000,"UpForSale":"2017-10-01"}

   ,
   

   {"Year":1999,"Make":"Chevy","Model":"Venture Extended Edition","Description":null,"Price":4900,"UpForSale":"2017-10-03T12:15"}

   ]' INTO @_json;
   SELECT JSON_VALID(@_json), JSON_LENGTH(@_json);
   Returns 1 and 2

4. SELECT '[ {"Year":1997,"Make":"Ford","Model":"E350","Description":"ac, abs, moon","Price":3000,"UpForSale":"2017-10-01"}

   ,
   

   {"Year":1999,"Make":"Chevy","Model":"Venture \"Extended\" Edition","Description":null,"Price":4900,"UpForSale":"2017-10-03T12:15"}

   ]' INTO @_json;
   SELECT JSON_VALID(@_json), JSON_LENGTH(@_json);
   Returns 0 and null

5. SELECT CONCAT('[ {"Year":1997,"Make":"Ford","Model":"E350","Description":"ac, abs, moon","Price":3000,"UpForSale":"2017-10-01"}

   ,',
   '

   {"Year":1999,"Make":"Chevy","Model":', JSON_QUOTE('Venture \"Extended\" Edition'),'"Description":null,"Price":4900,"UpForSale":"2017-10-03T12:15"}

   ]') INTO @_json;
   SELECT JSON_VALID(@_json), JSON_LENGTH(@_json);
   Returns 0 and null
