I have changed the APP to platform number 2.2 and facing issues with the local testing as during the local testing, it is not able to detect the functions through the invoke method.
Please let me know if this is an issue or bug or there is some other method to do local testing except ?dev=true
Have you followed the migration guide from this Wiki article?
Could you ensure if the SMI function has been registered in the manifest.json file of the app?
If everything is done, could you share if you see any error in the browser console when trying to use SMI?
