SharePoint Search issue resolving result source by name through API

Question

During last weeks we are experiencing some issues on different tenants with Search in SharePoint. We are doing requests to the API to search and we are providing the result source name. During this last days, SharePoint seems that is not resolving properly the result source. For instance...

https://xxxx.sharepoint.com/_api/search/query?querytext=%27*%27&rowlimit=30&selectproperties=%27Path%2cUrl%2cTitle%2cAuthor%2cWrite%2cServerRedirectedEmbedURL%2cWorkId%27&clienttype=%27WebService%27&properties=%27SourceLevel:SPSiteSubscription,SourceName:Local%20People%20Results%27

it is being resolved as...

but in another tenant, where we don't have the issue, we have...

Is anyone else having this issue? Is there any official MS issue opened or workaround?

Thanks in advance

Answer 1

Finally, after some weeks, this was solved by MS. So, just as a suggestion, open tickets from all tenants where you could reproduce this kind of issues and try to speak with them to merge those cases. Thanks
