Cannot read waypoints file

[sporella]

Hello:

First, I want to thank you for this very useful application. It saved me a lot of time and headaches!

My issue is when I try to upload a waypoints file in gpx format, and I always receive the same error:

Unable to parse file xxx: TypeError: Cannot read properties of undefined (reading 'parse') 

Could you provide some clarification about the structure of the file to be uploaded?

Thanks!
