Lambda's getting 403 Error

Question

When I access lamdas on my AWS I get 403 access in the API in the network console of the browser and the red banner appears on the top without any error message. It was all working just yesterday! all other AWS services are working fine and I have cross checked the permissions as well on the IAM but nothing helpful. Any advise will be highly appreciated.

Try looking at Monitor > Logs for more details.

Are you accessing the lambda url or using AWS ApiGateway to call the lambda?

I was going to suggest that there is an IAM issue here - that your permissions to view/edit the Lambda functions have been revoked. If you're operating in an account that is part of a larger Organization then that might also have been done using a Service Control Policy for the OU that your account belongs to.

If those aren't the case, I suspect there is a browser issue. To test, disable browser extensions and ad blocking to see if that is the problem.
