AttributeError: 'ProfilerDebugPanel' object has no attribute 'dump_filename'

I enable the profiler and this happens:

I have to clear my cookies to make the error go away.

Environment:

• Python version: Python 3.12.5
• Flask-DebugToolbar version: 0.15.1
• Flask version: 3.0.3

According to the code, self.dump_filename doesn't get set unless DEBUG_TB_PROFILER_ENABLED is True. But if I enable that, I get this:

Set environment variant to resolve the issues like "no attribute 'dump_filename' ". DEBUG_TB_PROFILER_ENABLED = True DEBUG_TB_DUMP_FILENAME_FORMAT = {request.url} # other setting like: {request.method}, {request.path}

It seems that ProfilerDebugPanel().dump_filename attribute is undefined whenDEBUG_TB_PROFILER_ENABLED != True. Possible solution is to modify __init__(self, jinja_env, context={}) method, someting like:

         return bool(self.profiler)
