Some store operations (e.g. login as existing user) do not work, exception is shown:
System ErrorNo access rights granted to method
Store operations are made by the store's user who is assigned with a specific
Store Full Access role. An exception can occur in the following cases:
a) when the user's role has been manually modified;
b) when the user's role has been deleted from the system at all and store is not synced;
c) when the user's role has been deleted from the system at all and store was synced. The role was not properly reassigned because of the bug with id #PBA-83710 ("The user's access cache is not cleaned on store synchronization when the role is added").
a) add the privileges back to the role;
b) synchronize the store and do the point c);
c) add any different role to the store's user and delete it right away (to workaround the bug with id #PBA-83710).
