I'm using Magento Cloud Commerce 2.3.1.
I scheduled an Update with the Staging tool on a Content Block. From what I remember, once it was published, I saw an error on the front-end so I went back to the Scheduled update and edited it.
Once I saved it, it was fixed on the front-end but when I go in the admin to access my Content Blocks, I have an error message saying "Item (Magento\Framework\View\Element\UiComponent\DataProvider\Document) with the same ID "244" already exists."
This ID is the content block I was editing. So it seems that something went wrong the last time I saved it.
I already took a look in the DB to see any unusual stuff and found that the table cms_block_store didn't referred a row linne in the table cms_block.
I removed the row in cms_block but the problem is still there.
Consequently, when I want to access my categories in the admin (Catalog / Categories) the maintenance page is displayed.
Can somebody help me?
Solved! Go to Solution.
Please check table/query of data provider "Magento\Framework\View\Element\UiComponent\DataProvider\Document" , and check with table there should be duplicate rows. Remove duplicate one and try.
Hope it can help you!
