Issue Description

When I try to query object from my database (based on back4app) with email that contains +(plus) characters I got Parse Error "Object not found". If I try to query objects with email that contains other special characters- "_" or "." everything working ok.

Steps to reproduce

• create _User object with email that contains +(plus) character. For example "[email protected]"
• fetch parse object from swift code (example with login below )

    func login(user: ParseUserObject) async throws {
        guard let email = user.email?.lowercased(), let password = user.password else {
            throw ParseError.Code.unknownError
        }
        // Fetch username from Parse(user provide only email/pass for login)
        var constraints = [QueryConstraint]()
        constraints.append(equalTo(key: "email", value: email))
        let query = ParseUserObject.query(constraints)
        let parseUser = try await query.first()
        // or you can use
        // let query = ParseUserObject.query("email" == email.lowercased())
        guard let username = parseUser.username else {
            throw ParseError.Code.unknownError
        }
        try await ParseUserObject.login(username: username, password: password)
        setIsAuthorized(true)
    }

Actual Outcome

try await query.first() throw an Parse Error (object not found)

Expected Outcome

Existing object
