Thanks for the solution but still I am getting the same error and I can’t update the version for not because a lot of other things going on there. can you suggest any other solution

Please don’t mark a solution if it’s not a solution.
remove the unique part of it, to see if it changes.
Also is that the whole merchamts model from your models file ?
