Could not create foreign key constraint

There are two entities Main entity and a child entity. The delete rule was set to protect in child entity. 

Then by mistake, I changed it to ignore. Now when I am trying to revert it to protect it is giving me this error:

"Could not create foreign key constraint".

Need help on this.

Hello
  Delete that fk of entity B and create again(if possible) create again 

because its not regarding the rules its due to circular dependency so to give delete you need to give delete to both

Hi @Akshay Deshpande šŸš€ 

Thank you for the reply, luckily I found the exact row which was causing the issue in table B, so I have deleted that row and again set the delete rule to protect and it works.
