API gateway intermittently throwing error: could not retrieve WSDL :ISS.0088.9163

Hi,

We keep on getting the above error for API gateway SOAP APIs. When the error occurs if we de-activate and activate the same API it starts working.

Can anyone guide on this?

Earlier frequency was less but now it is increasing and creating production hazard.

Thanks in advance

Share more details about the version of API Gateway and current fix level of IS_core and API Gateway fix.

Its seems like there is issue in retrieving Core Data of API from from Internal Data Store.

  1. Is the issue happening for the API which you created for very first time ? Are its happening for the existing API . if so is there any changes to endpoint recently ?

  2. Did you promoted this API via manual Import or using continuous Integration.

  3. Try to download the compare the API Package from problematic environment with your lower environment ( working ). Do you see was there is any mismatch with the Gateway endpoint

  4. Set your problematic environment API Gateway logs to debug and try to analysis the logs during the issue and after deactivate and activate

Dear Dinesh,

Find my response.
1.Is the issue happening for the API which you created for very first time ? Are its happening for the existing API . if so is there any changes to endpoint recently ? - APIs are versioned or standalone , there is no pattern as such, endpoints are same

  1. Did you promoted this API via manual Import or using continuous Integration.- manual import

Will give try on your suggestions but meanwhile is it possible to have some suggestion, fix or work around, that can resolve it?

Thanks in advance

Hi Anamika,

if there is no changes to your end point. I would request or suggestion you to verify the exported package and try to verify the json file. Do you see any “/” is appended in your endpoint.

Also enable the debug log and test the service before export from lower environment and after importing the same package to higher environment.

if you don’t see any progress in your finding , I would suggest you to create support ticket for temp work around fix. Maybe your endpoint might malfunctioned.

Work around is already you doing by enabling and disabling the API.

Regards,
Dinesh
