I am updating an e-commerce with Magento, from version 2.1.18 to version 2.3.4 (I have verified that it also happens by updating to version 2.2.11).
Uncaught TypeError: Cannot read property 'after' of null at Object.insert (arrays.js:122) at collection.js:94 at Array.map (<anonymous>) at UiClass.insertChild (collection.js:91) at layout.js:433 at Registry._resolveRequest (registry.js:418) at Array.forEach (<anonymous>) at Registry._updateRequests (registry.js:400) at later (underscore.js:821)
Same mistake if I go to checkout.
I am verifying that the subtotals of the order are not loaded, I do not know if it is the consequence of the error or the cause of the error.
- I have disabled and deleted all the installed modules;
- I have disabled all unnecessary modules of Magento 2.3.4;
- I have deleted my theme and I am using the Luma theme;
- I deleted cache, indexes and static files and created everything again,
but the problem is always there.
