Ironsource and Fb bidding problem

Big big in ironsource and fb bidding. When I put ironsource ad in my app and open in phone. Then show me error

And my app crashed. When I remove ironsource ad unit then my app work perfectly. Please niotron fix this problem. This problem is in my new app.

@MrSidhartha are you sure this error is due to ad components?

I am not using applovin. I’m use ironsource and fb bidding.

Oh Sorry My bad
