I have this constructor in my class, which caches db-entries on startup:

    constructor() {
        console.log('Caching auth-states from db...');
        prisma.auth_tokens.findMany({
            select: {
                api_token: true,
                web_token: true,
                web_refresh: true,
                api_refresh: true,
                expires: true,
                username: true,
            }
        }).then((val) => {
            val.forEach(dbState => {
                this.authStates.set(dbState.username, this.dbToAuthState(dbState)!)
            })
            this.cached = true;
            console.log('Finished caching auth-states')
        }).catch(err => console.log('Failed to cache auth-states:', err));
    }

This is how I export it:

export const ASP = new AuthStateProvider();

I have an API route which is used to communicate between the middleware and the backend (edge-runtime issue, I'v already asked about that here 2 weeks ago for context).
Some how, I get Caching auth-states from db... and Finished caching auth-states on every time the api-route is fetched by the middleware (which is on every acces to a protected route since it is used to validate tokens).
I hope someone might have an idea, since it literally wore me out pretty bad, I just can't find the issue.
