[API] Application instances

In one of the next releases we will publish the experimental organization runtime environment for applications. This brings some breaking changes with it:

  • For the /application-instances and /projects/<id>/application-instances endpoints, the project can now be null (for applications with the new runtime environment)
  • The PANTARIS_PROJECT_ID environment variable may now not be set (for applications with the new runtime environment)
  • The projectId field in the calponia-instance cookie may now not be set (for applications with the new runtime environment)
