SQLGrammar Exception in integration tests on H2 Database - oracle

Question

#Query(nativeQuery = true, value = "SELECT *\n" +
"FROM TDED_VISITS v \n" +
"WHERE v.v_collected_data.assigneeId = ?")
List<Visit> findAllByAssigneeId(String assigneeId);
The above code is used in the repository, the purpose of the query is to return all "visits" that have a matching value with the value provided. This value is a single value from inside a JSON object in a CLOB in an oracle database such as below.
{"visitId" : 1, "assigneeId" : "agr512"}
The model is made with the associated field as below.
#Column(name = "V_COLLECTED_DATA")
#Lob
private String visitJsonString;
The errors in the logs are as below
Column "V.V_COLLECTED_DATA.ASSIGNEEID" not found; SQL statement:
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.springframework.dao.InvalidDataAccessResourceUsageException: could not prepare statement; SQL [SELECT *
FROM TDED_VISITS v
WHERE v.v_collected_data.assigneeId = ?]; nested exception is org.hibernate.exception.SQLGrammarException: could not prepare statement
Have also tried the below SQL query but given the error that the function JSON_VALUE was not found.
#Query(nativeQuery = true, value = "SELECT *\n" +
"FROM TDED_VISITS v \n" +
"WHERE JSON_VALUE(V_COLLECTED_DATA, '$.assigneeId') = ?")
Caused by: org.springframework.orm.jpa.JpaSystemException: could not prepare statement; nested exception is org.hibernate.exception.GenericJDBCException: could not prepare statement
Have spent a few days looking for similar problems for other people, but to no avail. Appreciate if anyone can help, thanks!

H2 does not support accessing JSON attributes. See here for a list of supported functions: https://www.h2database.com/html/functions.html
