Today we have migrated the existing application and native functions to a new icon structure. The icon field in the function.json is changed from a string value to an object.
What does this mean for you?
It means that when you publish your function, you will get a validation error and you need to change the icon field to the new structure.
The new structure looks like the following:{ "name": "ActionsIcon", "color": "Orange"}
You can find the available icons here
The available colors are:[ "Yellow", "Green", "Pink", "Orange", "Purple", "Blue", "Teal", "Grey"]
Check the following documentation for more information.
