Issue: ASSERTION ERROR: token must be declared [Expecting => null is not undefined <=Actual]

I encountered an error while working on my project. The only special thing I did was use oidc(openId) for authentication.

I made some changes to the bootstrap project and now the first component that is running is the home-main component, which includes the openId configuration.

The error message displayed in the console is shown in this image.

Answer №1

Upon examination, the issue was pinpointed to this particular section of the code, which is highlighted in the accompanying image

It became apparent that the problem stemmed from an incorrect package being injected into a key component within the project's architecture

Answer №2

After attempting to reinstall packages with no success, I decided to run npm update and miraculously the error disappeared.

It turns out that the update included a fix for the packages. I'm not entirely sure which dependency was causing the error in my application, but hopefully this solution works for you as well!

Answer №3

It seems that I encountered a similar error to yours I carefully studied the photo you shared first To identify where the errors were located

(app-component-base.ts:308:43)
(home-main.component.ts:28:5)
(home-main.component.ts:81:4)

Based on my analysis, I believe the issue lies within these sections, with a high probability I would pinpoint it to this specific line

(app-component-base.ts:308:43).

Fortunately, my problem was very similar and was resolved using the same approach

I hope this information proves to be helpful for you
