Hi @jhaddix @ttymeh !

Yes, this error happens to few people and I have not been able to isolate because happen. The line BurpBountyExtension.java:129 is in the function:

@Override
    public List<IScannerInsertionPoint> getInsertionPoints(IHttpRequestResponse baseRequestResponse) {
        List<IScannerInsertionPoint> insertionPoints = new ArrayList();

        try{
Line 129->   IRequestInfo request = helpers.analyzeRequest(baseRequestResponse);

            if (request.getMethod().equals("GET")) {
                .....
            }
        }catch (NullPointerException e){
            return insertionPoints;
        }
        return insertionPoints;
    }

As you can see, I try to fix it with a big Try/Catch for non NullPointerException returned...but not is the solution.

I would need to connect to a remote machine through teamviewer or similar to debug the extension in-place, since I can't reproduce that error on my machine.

I think I know someone who happens to him, I will ask him to let me connect to see the root cause and be able to solve it

Thans for the issue!

I figured it out (for me at least).

Turns out the path that Burp was attempting to retrieve the .bb templates from was a protected path (C:/Program\ Files) in Windows (needs admin to write/read). I simply specified a new folder for the templates on my desktop and it started working!

Sorry for the alarm!

Solved, I was changed the default directory from user.dir to user.home.

Thanks to all!
