Unable to create instance from the Google Cloud SDK in a project or browse instances - google-app-engine

Question

I am unable to connect to a project on Google Cloud using the cloud SDK. I want to upload file on my instance using SDK. The error I am getting is:
You are now logged in as [ishanatech#gmail.com].
Your current project is [Trial-2015-1]. You can change this setting by running:
$ gcloud config set project PROJECT
C:\Program Files\Google\Cloud SDK>gcloud compute instances list

Answer 1

If you look carefully at the complex RE the error message displays:
'(?:(?:[-a-z0-9]{1,63}\.)*(?:[a-z](
?:[-a-z0-9]{0,61}[a-z0-9])?):)?(?:[0-9]{1,19}|(?:a-z?))'
you'll spot that all the letters there are lowercase -- always carefully expressed as a-z.
Trial-2015-1 starts with an uppercase letter, thus it's not deemed a valid project name.
Are you sure that your project isn't actually named trial-2015-1, with a leading lowercase initial...?

Error creating instance: googleapi: Error 400: Invalid value for field 'resource.name': 'Bastion-server'. Must be a match of regex '(?:a-z?)', invalid
