error TypeError: Cannot read property '_id' of undefined

When I migrate from alpha to v3.0.0, had an error about user-permissions plugin:
error Bootstrap function in plugin "users-permissions" failed [2020-06-12T01:15:06.300Z] error TypeError: Cannot read property '_id' of undefined at dbPermissions.map.p (/usr/src/app/node_modules/strapi-plugin-users-permissions/services/UsersPermissions.js:267:59) at Array.map (<anonymous>) at Object.updatePermissions (/usr/src/app/node_modules/strapi-plugin-users-permissions/services/UsersPermissions.js:266:46) at processTicksAndRejections (internal/process/task_queues.js:86:5)

For reproduce the error, do the next:

1. Migrate from alpha to RC3 using MongoDB
2. Set port to 3000 and run serve

I guess that is something related to some DB collection but I'm no really sure

• Node.js version: 12.16.1
• NPM version: 6.13.4
• Strapi version: v3.0.0
• Database: MongoDB
• Operating system: Ubuntu

Not sure where you got Strapi v1.0.0 but that version hasn't been supported in over 3 years and was built before the Alpha.

@derrickmehaffy Sorry for that, the version is the last RC, the v3.0.0

[derrickmehaffy]

That honestly looks like you have some miss-matched versions or something odd going on with your db

Just a question, I jumped from beta 26 to RC 3.0.0. In that case, I have just to use strapi@beta for the installation? I was searching for a newest one but I did not find anything

[PhantomxJoker]

I found the, I was running my Docker with an old version of Node.

Thank you

I am getting the same error, but I did not upgrade anything. I am still running on v3.0.0-beta.20 since it was released. Interestingly everything works in dev (Ubuntu 16 LTS, Node 12.18.1), but not in production (Docker container with node:12.8.0-alpine).

@PhantomxJoker Which version of Node did you use in your container to make it work?

[PhantomxJoker]

Hi @hendrikgaffo ! I'm using the same version as you, but with the change I made a clean build too (using npm run build --clean). Not sure if did the trick, but worked for me

the same error, on strapi the same 3.0.5, in my mongodb user-permission-permission table, some data without role, so dbPermissions.map err

Thanks for the hint @weilaiqishi ... We resolved this by removing the document from MONGODB without role! But this should not happen again, observation was that when a route and controller gets edited inthe project directory, it throws this issue. Route and controller files should be replaced as a whole when promoting code from one env to another.
I am not sure if there are any other rootacuses for this issue.

Thankyou!!

Just ran into this out of nowhere... didn't even need to reset my db to get across it.
Strapi 3.3.4
