We could see this error when deploying a stack in AWS that contains an App Flow block. If we are doing through Cloudformation it’s possible we have added a new mapping to a field that doesn’t exist in Salesforce.
Let see an example of error
In this case, Field1__c and Field2__c are being mapped in App Flow but those do not exist in Salesforce or at least App Flow doesn’t have permissions to access them.
Resource handler returned message: “Invalid request provided: AWS::AppFlow::FlowCreate Flow

- Make sure the field exists
- Make sure you don’t have a typo in the field name
- Make sure the user used for the OAuth connection has necessary permissions. You could check Field-Level security or an existing permission set
- Try to recreate the connection and deactivate/activate the App Flow
