it seems bitrix.list() does not work correctly with SPA
To make my code work:
bitrix.list('crm.item.list', { entityTypeId: '138', select: ['ufCrm4_1654801473656', 'ID'] })
I had to change one line in the source code:
node_modules/@2bad/bitrix/build/main/client/methods/list.js:39
I changed it and it works:
...r -> ...r.items
