Microsoft.SharePoint.Client.ServerUnauthorizedAccessException: Access denied

[praveen]

We have a user with read access to site collection and full control access to a list. User is able to edit list using design forms however user is getting access denied while saving forms via SP forms

Please advise

Dear Praveen,
User doesn't need full rights to be able to open the designer and see the form, but in order to save a form user does need Full Control rights for the Site.
