Getting 500 error when trying to query my db with JPA-CodePudding

Here is the error I get:

Parameter value [\] did not match expected type [java.lang.String (n/a)]; nested exception is java.lang.IllegalArgumentException: Parameter value [\] did not match expected type [java.lang.String (n/a)]

I have a basic site that allows you to create a "song" that contains a title, artist and rating. You can edit/delete the songs and the app will display all the songs on the main page. It has a function to order the songs by their rating in descending order which works and a feature to search which only half works.

I don't understand what's wrong because it works when I use the feature to search the first time, then on the second search it always throws this error.

Digging a little deeper I think these error lines are relevant:

    at jdk.proxy3/jdk.proxy3.$Proxy112.findByArtistContaining(Unknown Source)
    at com.cshannon.lookify.services.SongService.findByArtist(SongService.java:50)
    at com.cshannon.lookify.controllers.MainController.search(MainController.java:105)

I can't understand why it thinks the string I am entering is an unkown source when it works the first time I do it without errors. I have tried changing the route from a Get to a Post and that doesn't make a difference.

The controller code:

@GetMapping("/search")
    public String search(
            Model model,
            @RequestParam(value="search") String search
            ) {
        
        if (search.isEmpty()) {
            return "redirect:/dashboard";
        }
        
        ArrayList<Song> songs = ss.findByArtist(search);
        model.addAttribute("songs", songs);
        
        return "search.jsp";
        
    }

The service:

// Find by artist
    public ArrayList<Song> findByArtist(String search) {
        
        return (ArrayList<Song>) sr.findByArtistContaining(search);
        
    }

The repository:

ArrayList<Song> findByArtistContaining(String search);

And if it helps here is the form I am using to get the string from the user:

<form action="/search" >
    <input type="search" name="search"  placeholder="Search" aria-label="Search"/>
    <input type="submit" value="Search Artists" />
</form>

Wow I figured out the issue. I don't know the low level explanation for this but for some reason it's an error with Spring Boot 2.6.6 and changing it to 2.6.3 in the dependencies fixed it.

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.6.3</version>

If you want to fix for both security issue CVE-2022-22968 and this bug, you can use spring-boot version 2.5.13
