My name is Tobias and I have an app for cyclists in which I am implementing a functionality in which users can upload activities in GPX format to their account. I am testing the api service and I am having an error that I cannot remove. According to all the documentation I was looking at the file I am sending is correct but the api tells me that it is not correct. I’m sending you the details of the tests I’m doing to see if you can help me figure this out. I appreciate your help. Have a good evening.
