codebuild project creation failed

Hi! I have a problem with codebuild project creation. I've created codecommit repository, put a dockerfile and a buildspec file into it , than i want to create codebuild project for image creation proccess. When i set up all settings in Create build project window and click create build project nothing happens. No error messages or anything else. I've also tried to refresh page, re-loggin into account, reboot my mac, but nothing help. But when i chose Source provider github- everything works correctly. What could you advice? Thanks!
