[LFF2106-InvalidDataSent] - Which field or variable was the problem?

Forms
Updated June 10, 2021
posted on October 14, 2019

I have a customer getting this message on a form they built, however the form has 6 pages worth of fields, so the usual 1 hour manual method of filling out each field individually and submitting is becoming too far fetched. Is there a systematic way to retrieve the field name or variable that is throwing the error?

There are two situations that may run into the [LFF2106-InvalidDataSent] error:

1. The fields on the form are deleted by designer after the user load the form

2. The session is disconnected as it take very long for user to fill the form.

For the first situation, we may be able to provide error message to indicate which field/variable cause it. For the second situation, please check what user authentication method does the Forms site use: Laserfiche Server or Laserfiche Directory Server? If it uses Laserfiche Directory Server, please check web.config under Forms folder to see whether it has "persistentSessionLifetime" attributes under federationConfiguration->cookieHandler, if it does, please remove that attributes.

Just to clarify, this in no way is regarding a field value not matching one of the allowed values due to javascript or calculations being configured?

In my history I have received this message immediately after opening and submitting the form, because javascript was setting a value that did not exist in a list, etc.

I even have posts regarding the subject

Hi Xiuhong,

We have an issue with a particular lengthy form that keeps giving this error from time to time....there is no issue with fields being deleted after form load, I'm sure it is timing out because this form does take quite a while to complete and clients sometimes come back to it.  However, I don't see that particular reference you mentioned and we do use LFDS, here is what we have under federationConfiguration in the web.config file:

<federationConfiguration>
      <cookieHandler requireSsl="false" name="LMAuth" path="/Forms" />
      <wsFederation persistentCookiesOnPassiveRedirects="true" passiveRedirectEnabled="false" realm="http://ct-lf2/Forms/" reply="http://ct-lf2/Forms/" issuer="https://localhost/forms/" homeRealm="urn:laserfiche:lfdsdb:lfds" requireHttps="false" />
      <configuration autoAppendSlash="true" enableReferenceMode="true" />
    </federationConfiguration>

 

Does this look alright?
