We have a power automate flow which uses the Plumsail Create Modern Sharepoint Site action to create a new site when a new project is added to a sharepoint list. This was working well until this week. We are now receiving a "Root Element is missing" error, with the URL being stated as 'Null' in the results and the site is not being created. Nothing has changed in the flow since it last worked.
I have tried the following.
- Removed and readded the 'created modern sharepoint site' action
- re-entered the plumsail connection API key
- checked site creation is functioning within sharepoint admin (it is working)
Can anyone provide any help as to how to get this action working?
the redacted raw inputs are:
{
"host": {
"connectionReferenceName": "shared_plumsailsp_1",
"operationId": "FlowV1SharePointFlowJobsCreateModernSitePost"
},
"parameters": {
"siteType": "CommunicationSite",
"request/Url": "https://companyname.sharepoint.com/sites/H25016",
"request/Title": "H25016",
"request/Description": "description text",
"request/Lcid": 1033,
"request/AllowFileSharingForGuestUsers": true,
"request/Classification": "Internal"
}
}
And the resultant output:
