[LFF502-UnexpectedError] Unexpected error after 10.2 upgrade

Forms
Updated March 22, 2017
asked on March 20, 2017 • Show version history

I upgraded to 10.2 and we have received error "Laserfiche has encountered a problem. An unexpected error has occured. [LFF502-UnexpectedError]" on few of our forms - in the approval task step. Both forms have worked perfectly fine before the upgrade.

Any idea why this is happening and how to fix it? Here is the Event Viewer error message:

An unexpected error has occurred. [LFF502-UnexpectedError]

You can run following query on your database to filter the fields in all:

  select * from [dbo].[cf_fields] where [type]='date' and [format]is NULL

The run following query to fix them:

update [dbo].[cf_fields] set format='MM/dd/yyyy' where [type]='date' and [format]is NULL

Thanks Xiuhong, this fixed the issue. It seems like the date format wasn't fixable by GUI, only through SQL. Thanks again so much!!

From the log, it may be because the date format is null in database. You may want to try to apply the hotfix 1013831 (the null date format is 153935) for Forms 10.2.

Thanks Ming, how do I know if I already have that hotfix - I think it came with the version I downloaded (on March 15th).

The hotfix is version 10.2.0.789, since your Forms version is later than the version, it should have already included the hotfix. So I suppose you need to open a support case like Xiang said.

What is the exact version of Forms are you using? It seems you have applied the Forms 10.2 Update 1 from the other post: https://answers.laserfiche.com/questions/117430/102-Forms-changed-date-format#117485

If you are already on 10.2.0.834, please open a support case with your VAR by providing the download process.

We had the same issue. LF Support assisted and now fixed:

 

Open the formsconfig web page

Click on the Database page

Rename the database to any random name

Click Save

Rename the database back to the original name

Click Save

Restart the Forms Service

Hi Lidija,

I got the same error when submitting a form that contained a read-only date field with null format.

Can you check your process if there is such a date field, and correct the format setting?
