Issues with integrating PowerApps with Custom Connector in Studio Mode

(0) ShareShare
ReportReport
Posted on by sthota 139
Hello Team,
 
We are trying to connect to the Azure APIM instance through PowerApps. We were facing CORS issues in testing the custom connector response as well as hitting the same API through the APP URL in published mode.

 

We were able to resolve the above issues by referring to a couple of articles (https://powerusers.microsoft.com/t5/Connector-Development/Property-quot-quot-type-mismatch-Expected-...
) by adding https://flow.microsoft.com and https://apps.powerapps.com. URIs to the CORS policy.

 

However, we are still having issues with loading the data in PowerApps Studio mode. We tried adding the below URLs to the CORS policy after debugging in the network tab without any luck.

The error that we are seeing in the studio mode has been attached. 

It would be great if you could share your insights into this issue.

Thanks,
Srinivas

    Hello Srinivas,

     

    I was facing the same issue and was able to work around the issue by allowing all origins in the CORS policy. Like so:

     <cors>
 <allowed-origins>
 <origin>*</origin>
 </allowed-origins>
 <allowed-methods preflight-result-max-age="300">
 <method>*</method>
 </allowed-methods>
 <allowed-headers>
 <header>*</header>
 </allowed-headers>
 <expose-headers>
 <header>*</header>
 </expose-headers>
 </cors>

     

    The call works with this configuration, but is obviously not secure and cannot be used in production. 

    Were you able to find the correct URLs to be allowed for the connection to work?

     

    Thanks,

    Shridhar
