In WSO2 APIM Publisher getting error html response with 200 OK status

Question

I am getting error html response when using wso2 publisher hostname to get an Api value but with original endpoint it returning correct response. https://wso2apim-publisher-route-wso2-deploy.apps.cloud.admcoecloud.local:443/customer/2/api/customers/test/hello

http://customerinfo-javapipeline-dev-apps.apps.cloud.admcoecloud.local/api/customers/test/hello I am getting correct response.

I imported the swagger file in API publisher and I was expecting to get correct response.

I checked in Postman response for this API with WSo2 302 response is coming. Postman console response
