PostgreSQL parameterized query in Spring repository

I am using Spring framework and PostgreSQL database .In the following query I want to select those rows which have product name matched by the parameter `keyword' When I run the following query it gives me the following error

Does anybody tell me how to write right query ?

Query:

@Query(value="Select pp from product_photo pp join products p ON pp.product_id=p.id Where p.name ~* ?Keyword",nativeQuery = true)
    List<ProductPhoto> trail(@Param("keyword")String Keyword);

API:

http://localhost:8080/productPhotos/search/trail?keyword=Bottles

Error:

could not extract ResultSet; SQL [n/a]; nested exception is org.hibernate.exception.SQLGrammarException: could not extract ResultSet
