Hi Sjors,
unfortunately I no longer have the errors as skipping the run app stage and continuing with applying the security fixed them.
I do think the security section on Crash Course needs rewriting – it is a bit all over the place.
Hi all,
I just came across the exact same issue, indeed the crash course needs rewriting since this issue will occur to anyone that's following the course step by step.
At step 9.4.3 the roles are not set up correctly just yet, but the guide is telling you to run the app while it is impossible at this stage.
Continuing the course and refining the roles will probably solve it for me as well, but as a beginner this can be quite confusing.
