Hi everyone,

When a user finishes the survey, we have a pdf export button, where it downloads the pdf.

When that buttons is pressed the following error appear:
 

I founded that the solution was to enable the JSON-RPC option on global configuration, but it didn't work.

Thanks for your time

Using Limesurvey version: 3.27.19+210928
 

This "pdf export button" comes from where? Limesurvey? A plugin? Own script?

Hi holch,

The pdf export button its an own script that uses the get_access_key function, but this function drops the error from the jsonrpcclient

But if it is your own script that triggers the error, how can we help?

I mean, the error comes from the jsonrpcclient which we use on our script.

And as I saw that this error was fixed by enabling the JSON-RPC on global configuration, I thought someone could help me.

We don't have any information here.

But more : we all answer in spare time on forum.

Hi Denis,

I understand and I really appreciate it.

I will give you more information:
 

On line 4 comes the error, when we try to get_session_key.

Hi everyone,

We finally fixed the issue, if someone has the same problem as me, the solution was to take care on the url that is created on the interface part:

 
 

As you can see in the same image that I posted before, the remotecontrol link wasn't in the appropiate way.
 

The LSRC2 URL are shown on global settings, it was adapted to your current configuration.

Maybe need a warning box here …
