Unable to save Form and getting "Invalid Update" errorIssue While trying to save a form getting an "Invalid update" error and the form fails to get saved. CauseWhen a form doesn't get saved and gives an "Invalid update" error it is likely because one or more fields on the form view have an invalid value in it. The field causing the either does not support the inputted value or is unable to create a reference in the case of the reference field.ResolutionIn order to troubleshoot this issue, start removing the field from the form view to check which field is causing the issue. Please note, erroneous could be visible or hidden from Form view. An example of this issue is: A reference field is filled with a value that doesn't exist on its referencing table records. Thus causing the display of an "Invalid Update" error. Workaround for such issues is to remove such fields from view. A fix for the issue would be to add the correct value to the erroneous field.
