'scheme' error in app json

I am facing error while creating a build for my ios app. The error is related to ‘scheme’ field in my project’s app.json & is as follows:

Error: Problem validating fields in app.json. See https://docs.expo.io/versions/v32.0.0/workflow/configuration/
• Field: scheme - ‘scheme’ should be a string beginning with a lowercase letter followed by any combination of lowercase letters, digits, “+”, “.” or “-”.

Also getting up a warning while starting up the project. If i make it lowercase then it all starts to work, but I cannot make that change since I have deep link generated for my project & shared with people.
how do I resolve this issue?

Hey @garimap, sorry about this, but the scheme does need to be all lowercase. We’re updating the docs now to reflect this!

Thank you for pointing this out :slight_smile:
