# Which Problems Are Solved

In integration tests there is waiting for the application, but the
project is also included if the token can be created.

# How the Problems Are Solved

Wait for project not only for the application in the integration tests.

# Additional Changes

Some more corrections in integration tests.

# Additional Context

None
