Get-Item not working with SharePoint item with multiple object picker

[Stanislawo]

Hi All,

I'm trying to use the get-item flow operation on a list item which has a fields that allows multiple objects and get the error:

ResponseSwaggerSchemaValidationFailure. The API 'sharepointonline' returned an invalid response for workflow operation 'Get_item' of type 'OpenApiConnection'. Error details: 'The API operation 'GetItem' requires the property 'body/Approver' to be of type 'Object' but is of type 'Array'.'

I want to start a flow using a button and then get the item properties with get-item. Is there any way I can work around this error?

Here's a couple pictures showing roughly what I've set up:

Any help would be much appreciated!

Best,

Stan

@Stanislawo Ideally Get item action with multiple selection people column works for me.

Can you try deleting the 'Get item' action, re-adding the action and Save?
