HTTP 500 error using search API for objects with ~ in the name

We have an object with a ~ in it’s name, if you search for that object Nexus responds with a 500 error e.g

curl '' -v


> GET /service/rest/v1/search?group=&repository=apt&format=raw&name=test/foo~bar HTTP/2
> Host:
> User-Agent: curl/7.58.0

A tilde is a special character in elasticsearch. Can you try adding a backslash in front of it?

thanks escaping the tilde does work, however a 500 error seems wrong if it is a bad request

or could you possibly handle escaping the tilde in the server during the request?

Yes this seems like a bug to us - a 400 error would probably be more appropriate in this situation.
