Check whether the firmware versions of the drone and the dock are compatible. For specific matching versions, you can check the release note of the dock or the release note of the Cloud API.
- Check whether the url in the flighttask_prepare task is correct, enter the url in the browser, and it needs to be able to automatically trigger the download.
- Check whether the dock network can access the url in the flighttask_prepare task.
- Check whether the cloud service normally responds to "Get the wayline task resource" interface requested by the dock.
- If the same route file can be executed normally sometimes, but an error is reported sometimes, it is necessary to check whether the dock network is stable.
