When importing your Sketch prototype, we check the initial screen in the prototype for hotspots. If we don't find any, we will present the following error:
"This is not a Sketch prototype. Try creating Links between Artboards and try again."
This error most commonly occurs when you haven't defined a starting screen for your prototype or if that defined starting screen does not have any defined hotspots.
To define a starting screen for your Sketch prototype:
- Select the artboard in your Sketch file that you want to use as the starting screen
- Verify that it has at least one hotspot connecting it with another artboard
- Click Prototype > Use Artboard as Start Point in the top menubar
- Re-publish your document to Sketch Cloud
Once you've done this, you should be able to re-import the prototype into Maze without error.
