Suspended Task When Trying to Email User

Forms
Updated April 30, 2021
asked on April 29, 2021

I have a form that when the process is Rejected by a supervisor, it is supposed to email the original user that filled out the form.  

I have noticed that when the process is Rejected by the supervisor or some other user, it gets suspended.  

Below is the log:

[LFF502-UnexpectedError] Details: URL: Error: UnexpectedError Date: 4/29/2021 3:50:00 PM (Pacific Standard Time) HTTP Status Code: 500 Business Process ID: 6 Instance ID: 4436 Business Process Name: Expense Reimbursement Form Stack Trace: Caught exception: Laserfiche.Forms.CommonUtils.Exceptions.LFFormsException Message: An unexpected error has occurred.

Go to the Expense Reimbursement Form Process and open up the email service task that is getting stuck on the email to the initial submitter. In the right pane of the email service task, scroll down to the Body section and look to the right. There are two tabs, HTML and Visual. We think something is incorrect in the HTML side. Here's how I would fix it. 

Select everything in the Visual side and copy it. Then delete it all. Then paste it back in. I think this will get the HTML to re-write itself. 

If that doesn't work, click the HTML tab and copy that here into the Answers post using the {Code} button above. That way we can view the HTML and see what's wrong.

Hi Manuel,

The error message indicates something wrong happens when Forms trying to parse the body of email. For example, we've seen this error with html tag in variable token (like {/dataset/Single_Line</font></u></a>}). 

Could you review the configured email content in HTML view to see whether there is anything similar or suspicious?

Hi Ziyan,

How do I do that?  Do I need to go through every variable and look for HTML content?  

I am lost at what you are describing.

Thank you,

Manny

That fixed it, but I removed the Dataset that I was trying to call up.  I am going to try to put it back and see what happens.  

Before:

"Hello {/dataset/Name_of_Employee},

Your Travel Reimbursement Form was Denied by your Supervisor.

Thank you."

After:

"Hello,

Your Travel Reimbursement Form was Denied by your Supervisor.

Thank you."

 

Thank you for the help.

Putting it back should work. There may have been a typo on the HTML side before and the dataset accidentally was {/dataset/Name_of_Employee,} with the , before the } or something like that.
