Answer 1

I had this issue when deploying my app to Google App Engine. I found that by moving "nunomaduro/collision": "^2.0" from "require-dev" to "require" in my composer.json fixed this problem.

Answer 2

• move nunomaduro/collision: ^2.0 from require-dev to require in composer

If that doesn't solve the problem, try

• deleting the composer.lock file
• uploading the project again without this file (it solved it for me)
