 Description   

According to https://mariadb.com/kb/en/jsonpath-expressions/ a path expression with special characters can be quoted as shown below. But doing so returns NULL rather than the JSON data it should. Example is hierarchy from a Chrome Lighthouse report. 

SET @json = '{"audits":{"first-contentful-paint":{}}}' ;
 
 
 
SELECT
 
JSON_VALID(@json),
 
JSON_QUERY(
 
	@json,
 
	'$.audits'
 
),
 
JSON_QUERY(
 
	@json,
 
	'$.audits."first-contentful-paint"'
 
),
 
1;

The below had previously worked in 10.6

JSON_QUERY(
 
 
 
	@json,
 
 
 
	'$.audits.first-contentful-paint'
 
 
 
)

Thank you! This is the same bug as MDEV-29586, so I will close the report.
