Invalid form data was sent to the server

asked on July 22, 2020

I'm getting this error when some users are submitting a form through public portal. I think it's a timeout issue but it was my understanding that the session is saved in the database regardless and once submit is pressed it retrieves the info even if the session has timed out.

Invalid form data was sent to the server. There is no active session for this submission. This can occur if the previous session is disconnected. [LFF2115-InvalidDataWithInvalidSession]

Details:

URL: /Forms/Form/Submit

There are some session data stored in the memory of IIS web application, if the FormsAppPool application is recycled after user open the form and before user submit the form, user will get InvalidDataWithInvalidSession error. Forms 10.4.4 add the ability to recover the fields data user entered when they run into such error (https://support.laserfiche.com/kb/1014169/list-of-changes-for-laserfiche-forms-10-4-4), you can update your Forms server to have the ability to recover form.

Did you see the "Recover form" action when you ran into this error?
