Issue when accessing the GraphQL service on denodo

Denodo version 8 followed doc at https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/restful_architecture/graphql_service/graphql_service Upon visiting the service http://denodo:9090/denodo-graphql-service/graphql/<our-database-name>/schema.json We get Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. Fri Apr 16 13:08:22 UTC 2021 There was an unexpected error (type=Bad Request, status=400). Error obtaining the connection: HikariPool-1 - Connection is not available, request timed out after 30000ms.

Hi, If I face such an error, I would check if the Virtual DataPort server has been started and GraphQL service has been deployed correctly before making a request to Denodo GraphQL Service. For your scenario, you could also perform the following steps: * Check the **vdp.log** file located under ‘<DENODO_HOME>/logs/vdp’ folder for possible errors or look for the log entry like below: * com.denodo.tomcat.manager.TomcatManager [] - 'denodo-graphql-service' has been deployed. * Restart the Virtual DataPort server instance and check if the error gets resolved. * Using Postman, check if the *Authorization Header* has been configured correctly. You can also take a look at [**Schema**](https://community.denodo.com/docs/html/browse/8.0/en//vdp/administration/restful_architecture/graphql_service/graphql_service_schema) section of the Virtual DataPort Administration Guide for more information. If you still need help and you are a valid support user, you can raise a support case at [**Denodo Support Site**](https://support.denodo.com/) so that our Support team will assist you. Hope this helps!
