I am trying to update person/group column using power automate . I am getting below error
An unexpected 'PrimitiveValue' node was found when reading from the JSON reader. A 'StartObject' node was expected. clientRequestId: bbf41a14-51dd-4cd0-8ac8-67313f4cf6a5 serviceRequestId: 539c869f-a0d9-b000-66c0-1ac6d790fbd9
I am able to successfully retrieve the user ID but the update fails.
{ '__metadata': { 'type': 'SP.Data.Partner_x0020_Training_x0020_RegistrationListItem' }, 'RegisteredByStringId': '[@{variables('UserID')}]' }
When i query using link below, the results for my "RegisteredBy" column are as below
https://siteurl/Business%20Development/_api/web/lists/getbytitle('Partner%20Training%20Registration%20Hub')/items(96)
Business%20Development/_api/web/lists/getbytitle('Partner%20Training%20Registration%20Hub')/items(96)
<d:RegisteredById m:null="true" /><d:RegisteredByStringId m:null="true" />
TRied using both these column names but no luck.
