Service Now GetKnowledgeArticles action rank property data type error

Posted on by sriram_v

I am trying to use ServiceNow GetKnowledgeArticles action from Power Automate flow but the flow run fails with the below error

The API 'service-now' returned an invalid response for workflow operation 'Get_Knowledge_Articles' of type 'OpenApiConnection'. Error details: 'The API operation 'GetKnowledgeArticles' requires the property 'body/articles/0/rank' to be of type 'Integer' but is of type 'Float'.'

From the servicenow connector article ServiceNow - Connectors | Microsoft Learn data type of Rank property is of type integer.

How do I resolve the issue,

Regards

I initially had the same error but got it fixed by putting the input query in quotes:

Hi Henry

Thanks for the suggestion. I tried adding the query in quotes but still getting the same error.

You're right, this doesn't fix the issue, the symptom disappears because there are no results.
It looks like the ServiceNow Knowledge API doesn't return data in the expected format anymore. Maybe a breaking change on their side, I don't know.

I would suggest to raise a support request for this: Get Help + Support in Power Platform - Power Platform | Microsoft Learn

In the meantime, perhaps try to make a direct HTTP request to achieve the same with the HTTP connector or with an custom connector? The API appears to be documented here: Knowledge Management REST API (servicenow.com)

Seems the issue is fixed now. I am able to get knowledge base articles from Service Now using ServiceNow GetKnowledgeArticles action.
