Like Pankaj Mishra say, it is really. The APPIUM Desktop UI have some bugs and the only way to solve this problem it's typing the capibilities directly in the fields and never copy paste or edit like a JSON format.

APPIUM Desktop UI have some bugs as a result you get this error even if the capabilties are present. You can refer Here to avoid above issue.

Based on your screenshot, you made a spelling mistake:

flatformName: android

flatformVersion: 8.1

You need to fix f to p and it will work perfectly for you!

Solution 4:[4]

Make sure you enter "platformName". Not "platformName ". Can you see the difference? Second one has a hidden space which could often happen when you copy-past the capability name.

Solution 5:[5]

make you've write correct words "platformName:" and check your json representation.
