Unable to catch MethodArgumentTypeMismatchException on doFilter()

I have a filter that basically logs incoming and outgoing information, but it seems that using this custom RequestLoggingFilter implements Filter creates a problem, I get MethodArgumentTypeMismatchException when a request's URI is unmapped. Error as follows:

org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; For input string: "all"
...
dev.realtards.kuenyawz.filters.RequestLoggingFilter.doFilter(RequestLoggingFilter.java:54) ~[classes/:na]
...
Caused by: java.lang.NumberFormatException: For input string: "all"

org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; For input string: "all"
...
dev.realtards.kuenyawz.filters.RequestLoggingFilter.doFilter(RequestLoggingFilter.java:54) ~[classes/:na]
...
Caused by: java.lang.NumberFormatException: For input string: "all"

I believe adding the non-existent URI "all" which I don't even map caused this problem. I find it weird since I could not catch the exception in:

Somewhy it got filtered

RequestLoggingFilter...

on the catch, I have tried adding the exception and Exception, but the error could not be handled by my overridden doFilter() method. It could only be handled by my global advice exception handlers, specifically the MethodArgumentTypeMismatchException handler, where I don't want that! I want it to return some kind of 404 since the handler is not found

It never went through the catch. It is also important to see that the error came from the servlet handlers:

I'd like a guide on this handling. Or is there a simpler approach? Such as denying the request with 404 (I'm trying to do that) Severity: clogs the logger Currently doing this goofy ahh handler:

    @ExceptionHandler(MethodArgumentTypeMismatchException.class)
    public ResponseEntity<ErrorResponse> handleMethodArgumentTypeMismatch(
        MethodArgumentTypeMismatchException ex) {

        String message = "Endpoint does not exist";
//        message = String.format("Failed to convert value '%s' to type %s", ex.getValue(), Objects.requireNonNull(ex.getRequiredType()).getSimpleName());

        return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(new ErrorResponse(message));
    }

    @ExceptionHandler(MethodArgumentTypeMismatchException.class)
    public ResponseEntity<ErrorResponse> handleMethodArgumentTypeMismatch(
        MethodArgumentTypeMismatchException ex) {

        String message = "Endpoint does not exist";
//        message = String.format("Failed to convert value '%s' to type %s", ex.getValue(), Objects.requireNonNull(ex.getRequiredType()).getSimpleName());

        return ResponseEntity.status(HttpStatus.BAD_REQUEST).body(new ErrorResponse(message));
    }

Wait Wait a minte\ maybe it's because it's trying to access GET /api/products/{productId}, but instead of Id, the provided thing was "all" which does not make sense and should throw that tehee
