Error encountered = "Error: A parameter cannot be found that matches parameter name 'ReturnType'."

The documentation clearly mentions the parameter "ReturnType" for the cmdlet Add-PnpField, provided the "Calculated" type is set as well.

This is failing:
Add-PnPField -DisplayName $ctTypeField.Displayname -InternalName $ctTypeField.Name -Type $ctTypeField.Type -Formula $ctTypeField.Formula -ReturnType $ctTypeField.ReturnType -Group "Contract Columns"

While removing the ReturnType parameter and value from the command works as expected (but sets the OutputType to "Text").

Seeing that there is a value 'OutputType' in the output for Get-PnpField, I have also tried using the parameter "-OutputType" instead of "-ReturnType", but that failed as well (to be expected, I guess, as this is not documented)

I also tried using Set-PnpField to set the value of "OutputType" after adding the field, but that failed with an warning that I should not use the string "Number": "WARNING: Setting property 'OutputType' to 'Number' failed with exception 'Object of type 'System.String' cannot be converted to type 'Microsoft.SharePoint.Client.FieldType'.'. Value will be ignored."
