Unable to embed superset dashboard in an iframe from an angular application

[HariniPuppala]

Hi,
I am trying to integrate superset dashboard into an angular based web application by embedding superset dashboard in an iframe.
I did the following setup:
Configured LDAP Authentication in superset.
Enabled a Custom Security Manager to authenticate based on a jwt-token. The jwt-token is decoded and the credentials are validated as per the configured LDAP settings in the Custom Security manager.
The jwt-token based authentication is working as expected and I am able to redirect to the dashboards without the login page. But, the same is not working when passed in an iframe.

Getting the below error in iframe:

There is this warning message in superset log:
WARNING:root:Class 'werkzeug.local.LocalProxy' is not mapped

Can anyone please help on this. Thanks in advance!

I am also getting the same error after upgrading superset from 1.1.0. to 1.2.0
Does anyone know about this error.
