Context

• Due to recent changes, it is not possible to define a Project Key upon creation. If the project key pattern is defined with a value different than the default (i.e. Containing -, which is not supported), project creation will fail if it doesn't match the new pattern.

Symptoms:

• By creating a project through Projects > Create project, an error message saying "For some reason the magic didn't happen. Click create to try again." is returned.
  

Verifying the Problem:

• The application logs return an error message mentioning an IllegalState.Exception, as in the example below:

Workaround:

• Contact Atlassian support to have the project key pattern returned to default. This will imply updating all projects to the default template as well.

Note:

• As of August 2018, users can define the project key upon creation.
