FF4j + MS SQL : Getting "operand type clash datetime2 is incompatible with timestamp" Exception

Question

My Project Structure: Spring Boot + DB : MS SQL + FF4j (FeatureStoreSpringJdbc)

Created the table schema as below url https://github.com/ff4j/ff4j/blob/master/ff4j-core/src/main/resources/schema-ddl.sql

Getting "operand type clash datetime2 is incompatible with timestamp" Exception when accessing "/api/ff4j" rest api Is there any way to resolve this issue

Exception StackTrace: org.springframework.jdbc.UncategorizedSQLException: PreparedStatementCallback; uncategorized SQLException for SQL [SELECT count(EVT_UUID) as NB, EVT_NAME FROM FF4J_AUDIT WHERE (EVT_TYPE LIKE 'feature') AND (EVT_ACTION LIKE 'checkOn') AND (EVT_TIME> ?) AND (EVT_TIME< ?) GROUP BY EVT_NAME]; SQL state [S0002]; error code [206]; Operand type clash: datetime2 is incompatible with timestamp; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: Operand type clash: datetime2 is incompatible with timestamp
