Unhandled Rejection (TypeError): Cannot read property 'roles' of null

[eldyvoon]

this block of code in firebase.js is throwing an error:

//if (!dbUser.roles) {...}

error
Unhandled Rejection (TypeError): Cannot read property 'roles' of null

As I can see, dbUser can't be null if there is authUser, so this error shouldn't happen if you don't remove the user data while it is authenticated

@edguerrade I didn't remove the user, the user exist in my db. But after I delete and reauth the user now it worked.

Hello, I'm a beginner in firebase, and have the same issue. DId you remove the user in firebase db to solve it?

I guess this bug happens when you are in between of the implementation of the authentication user and database user. My advice is to start from a clean slate by

• deleting the user in the Authentication Database (see Authentication Tab on Firebase Dashboard)
• deleting the user in the Realtime Database (see Database Tab on Firebase Dashboard)
• busting the cache of the application, because of local-storage (see screenshot)

Correct. I deleted everything and start over and it worked. I can't remember how to reproduce the bug though.

I had an issue and have been fixed by the start from a clean slate's guide. Danke.

I'm having the same issue

[rwieruch]

Did you try #24 (comment) @oximer ?

Tried. But doesn’t work. Followed all 3 steps. Still getting the same error. Although I started with a clean slate.

Can't purge the entire cache for some reasons.

Figured it out. Instead of defining the roles in Sign Up like roles[ROLES.ADMIN] = ROLES.ADMIN;
do roles.push(ROLES.ADMIN); And also initiate roles like const roles = []; instead of {};
