Unexpected error during swagger import

Hi,

In Postman 8.6.1 I tried to import APIs from:

https://pubhub.devnetcloud.com/media/dnac-api-docs-1-3-3-x/docs/Antman-swagger-v1.annotated.json

but continuously getting an error: “Unexpected error during import. Please try again.”

Can you advise how to tshoot / fix it further?

Thank you,
Mariusz
