Hi @Aveeva ,

Can you please try the quick hotfix given by ChameleonDevil on the below link:

https://github.com/magento/data-migration-tool/issues/813

Potential fix - but read notes below
I have created a committee to check for non-existing key. There are two changes in migrateCustomEntityAttributes(). This essentially just makes sure to skip non-existing IDs. After applying this to my local installation and running migrate:data on a backed-up

new M2.3.5 database, all the other steps continued without issue - took about 40 minutes.

Hope this helps you!

@Nishu Jindal  Really thank you for your support, 

I just came across a few forums that said a bug in Magento 2.3.5 data migration tool. https://magento.stackexchange.com/a/314906/57334

We have the plan to migrate to Magento 2.3.4.

Thank You @Nishu Jindal  for you fantastic support also @Bhanu Periwal

Hi @Aveeva,

Great .. That was my second thought if this hotfix is not going to work for you. 

Glad to know we found real issue.

Thanks!
