Hello Volodymyr, I did some research and found this error to commonly occur due to missing dependencies, environment files not found, or skipping/ignoring files or folders. You can refer to this Server Fault post <https://serverfault.com/questions/1004903/error-gcloud-app-deploy-error-response-9-cloud-build-bfe8bf5b-8368-4db6-a6> for example.
Since you are using python, my suggestion would be to first ensure that your application is in a virtual environment <https://cloud.google.com/python/setup#installing_and_using_virtualenv>, and to check that you’re not skipping/ignoring files using .gitignore, .gcloudignore <https://cloud.google.com/sdk/gcloud/reference/topic/gcloudignore>, or the skip_files flag on the app.yaml <https://cloud.google.com/appengine/docs/flexible/python/reference/app-yaml> . For future posts, do keep in mind that Google Groups are generally reserved for discussions and opinions about Google products, you may want to refer to Stack Exchange for how-to and technical questions since the answer-question format on those sites will give your question greater visibility. With that in mind, I hope this information helps point you in the right direction. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
