Hi Pavan,

You will see SECU0001 when you have additional properties that weren't expected in your post data. Examine the SECU0001 alert to see if we can get rid of the extra  properties to  make this go away

If you want to ignore this you can also use the below prconfig setting

<env name="security/unexpectedinputpropertyalert" value="false" />

Hope this helps!
