for v6 - There is no role with ID `org_uuid` for guard `api` about laravel-permission HOT 2 OPEN

It seems to me that you made some mistake in the configuration. Upload a demo repo with the code showing the problem
https://spatie.be/laravel-permission/creating-a-demo-app

from laravel-permission.

1. The "there is no role with ID x" error is thrown by Role::findById(), which is called from getStoredRole(), which is called by collectRoles(), which is called by assignRole().

2. Your posted assignRole() call looks strange. Why are you passing a nested array?

When reformatting your posted code of:
$userOrgManager->assignRole([$roleOrgManager->id => ['organization_id' => $organization->id]]);
it looks like this:

$userOrgManager->assignRole([
    $roleOrgManager->id => [
        'organization_id' => $organization->id
        ]
    ]);

That's not the kind of array that assignRole() accepts. assignRole() accepts a one-dimensional array of role ids or role objects/records or role names.

3. It should never be looking for a role with an ID of uuid (or org_uuid) ... that's part of the schema, not a valid record id. (If you were giving a role name of uuid, then perhaps "uuid" might be acceptable, but if it gave an error related to such a name, then it would say that it couldn't find a role with that name, not "ID".)
   Thus, as parallels999 mentioned, something is wrong in your code or your configuration.
   We need to see your complete code related to this. As mentioned, please create a fresh repository for a basic app which recreates this exact problem.
