Error when trying to create an item in sharepoint with multi-select choice field

(0) Share

Posted on by Brian2M

I am trying to update a multi-select choice field in a sharepoint list from flow. I keep getting the error

OpenApiOperationParameterValidationFailed. The 'inputs.parameters' of workflow operation 'Create_item' of type 'OpenApiConnection' is not valid. Error details: The API operation does not contain a definition for parameter 'item/Color'.

If I hardcode those array values in the Create item section it creates without any problems. It is just when I'm passing in an array to the multi-select choice field.

Below is the column definition in sharepoint and the flow they I created to update this column.

If I harcode it like the following it works without a problem.

If you look at the inputs for the Create Item step they both show the following:

{
 "host": {
 "apiId": "subscriptions/12345678-1234-1234-a1234-1234567890/providers/Microsoft.Web/locations/westus/runtimes/msmanaged-na/apis/sharepointonline",
 "connectionReferenceName": "shared_sharepointonline",
 "operationId": "PostItem"
 },
 "parameters": {
 "dataset": "https://sitename.sharepoint.com/sites/ABC/IT",
 "table": "1234-1234-1324-1234-123456789012",
 "item/Title": "Test2",
 "item/Color": [
 {
 "Value": "Red"
 },
 {
 "Value": "Yellow"
 }
 ]
 }
}

Anyone have any idea on this error, or another way to populate a multi-select choice field?

Hi @Brian2M ,

Please take a try with the following workaround.

Instead of inputting the value into a variable directly, please try with a Compose.

After the Compose action, initialize an Array variable.

Add Apply to each, select from Compose output, add Append to array variable within the loop, and input the following function in the Value field:

items('Apply_to_each')?['value']

Under Apply to each, add Compose 2 with the following code:

join(variables('Test'),',')

Add action Create item, in the Multiple selection enabled Choice column, select Compose 2 output as a custom value.

Best regards,

Mabel

@v-yamao-msft -

Tried your suggestion and the same error still comes up.

It appears in the input to the Create Item step that it is just representing the options as a standard array. Is this how your input looks?
{ "host": { "apiId": "subscriptions/12345678-1234-1234-1234-123456789012/providers/Microsoft.Web/locations/westus/runtimes/msmanaged-na/apis/sharepointonline", "connectionReferenceName": "shared_sharepointonline", "operationId": "PostItem" }, "parameters": { "dataset": "https://MySite.sharepoint.com/sites/ABC/IT", "table": "123456-1234-1234-1234-123456789012", "item/Title": "Test2", "item/Color": "Red,Yellow" } }

Hi @Brian2M ,

In the action Create item, for the multiple selection enabled column, instead of switching to input entire array, please stay with the detail inputs, and select the compose output as a custom value.

Best regards,

That appears to work, but the values do not appear to be selected in sharepoint.
Below is a manually entered item and the TEST2 entered from the flow suggestion. On the list they look exactly the same.

If I look at the Manually entered item it shows Red and Yellow selected.

On the item that was entered using flow the Colors do not appear to be selected.

My original logic is now working. Something must have been adjusted in the backend. I took one of my original flows that was failing at the beginning of the week and reran without modifying it and it now works correctly.

Thanks @v-yamao-msft for the suggestions, but changes must be rolling out and my tenant must have been having some issues.
