We certainly do not know; you did not provide a Block image showing what you are doing.
- You "made a version of the app and was modifying it using checkpoints"; you may have changed something in your latest checkpoint version of the app that causes the error. If you load a previous 'checkpoint' version; does that version run properly?
- There are many ways to get a 'route'. Are you using the Navigate control HOW TO: Use the Navigate control or are you using a different method? In this case of 'Navigate', the route is provided by openrouteservice.org . There might be an error communicating with their server or the server is experiencing heavy usage. Since the route information is provided by volunteers, the route provided (coordinates) might have an error.
- App Inventor 2 developers can provide something similar to using Navigate ; use the Map component but without the directions display or can use OpenStreetMap without the Map Component. Turn by turn map direction advice is also possible using the Google Directions api . Use it with a Google Map API key .
You might need to use a different method to find the route as described above. We don't know because you did not provide an example of your code Blocks. " there’s this new error yail-dividing error: is this a route different from one you tried before (different point to point - identical start and ending point)?
You posted several months ago ( Communication between two apps ) . Is this the same Project? Are you really attempting to derive a route or are you collecting geocoordinates and attempting to post the results of an actual trip on a Map component. In that case, most developers would call that collection of coordinates a trak or track. In that case LineString to draw a track might help. The example uses a LineString to plot a trak on the Map component.
Are you creating your own geojson from coordinates and plotting that using the WebViewer?
