Error Details:
Action 'Get_Invoices' failed: The API 'sharepointonline' returned an invalid response for workflow operation 'Get_Invoices' of type 'OpenApiConnection'. Error details: 'The API operation 'GetItems' requires the property 'body/value/0/Department' to be of type 'Array' but is of type 'Object'.'

Requirements:
- Diagnose and fix the error
- Ensure 'Department' property is correctly typed

Ideal Skills:
- Power Automate expertise
- SharePoint integration knowledge
- Experience with API error resolution
