When adding print of c (c, _ = gin.CreateTestContext(w)) and w (w = httptest.NewRecorder()) it looks like this..

Added outputs in following commits d64903b, 9271f64 and 3602f04.

To be reverted later when finished with testing.

[tobiasehlert]

Workflow doesn't have permissions required to access secrets since they are coming from a fork, which are required to connect to tibiadata's network.

Possible solution would be to trigger workflow by a command (eg. /codecov), but we don't have such thing implemented for now.

Workaround for now is for a tibiadata-developer to trigger codecov instead by pushing to branch.
