Cant access Magento 2.4.0 backend Could not create an acl object: Invalid Document

Question

I'm testing Upgrade to Magento 2.4 but getting the error below. I've read that this error can relate to a missing title attribute in a custom extension. To try and isolate teh issue I have remove all the extensions from /app/code/ folder and then ran upgrade , compile process again but the issue still remains even with all extensions removed.

Any idea how to debug?

1 exception(s):
Exception #0 (LogicException): Could not create an acl object: Invalid Document 
Element 'resource': The attribute 'title' is required but missing.
Line: 13

Answer 1

If your store operates with MSI disabled - the new modules you will also need to disable are prefixed with 'Magento_InventoryInStorePickup'

Disabling all of the Magento_InventoryInStorePickup modules fixed (could not create an acl object) in admin error for me.

Thanks user552769 for pointing in the right direction!

Answer 2

.. finally resolved. in 2.3.x I had disabled the inventory MSI modules but 2.4.0 add's some new modules. These need to be disabled as well. Then the acl error is resolved.
