Describe the problem/error/question

I was working on using N8N forms, using the multi-select dropdowns to record survey results, and was doing successfully, but now I’ve updated to latest N8N, it seems to be recording me a NULL even if I select all of the multi-select options.

After testing the form, I selected all 13 options of all 4 questions, and all of them return [NULL] (See image below)

Does anyone have any solutions? It was working right up until I updated my N8N to latest stable, could it be this?

Thanks!

Please post your workflow between ticks so we can have a look

Hi Sebas, I’m not so sure what you mean by this (I’m still relatively new to N8N)

This is specifically at the N8N Form submission Node, the rest of the workflow isn’t functional yet.

What I’m doing is using the Form to initiate as a trigger.

I test the form and fill it out completely (All options are 13 option multi-select drop down lists)

I fill out all the sections I marked as required, and then I hit submit.

The result is the output showing NULL for all the sections that were Multi-select drop down lists. The other parts of the form fill out fine.

P.S. Could you elaborate on what you mean by Posting the Workflow between Ticks? (Again, I’m still kinda new and unsure what you mean by this)

Hope this provides some more information :slight_smile:

Thanks for the reply!

Hey @n8nnoob, welcome to the forum! :slightly_smiling_face::partying_face:

Can you try updating to 1.84.0 that was released to beta yesterday? It should have been fixed in that version.

This worked haha.

So simple, I feel silly for not trying.

Thanks!

Is it good practice to use the Beta versions?

All good & please don’t feel silly! I’m the product manager for the Nodes team at n8n, and was aware of this bug and that we fixed it yesterday. :slight_smile:

Regarding “good practice to use beta versions”:

  • For production use cases, I would recommend you stick with the latest stable versions, unless there is a bug fix like in this case that is absolutely critical for you to adopt asap.
  • To try new things, explore new features & nodes, it can make sense to have a separate beta instance, maybe just to play with locally.

Ah, that makes sense!

Thanks so much @pdwarf

I will have a look into new features & nodes.

Hello! I’m in the 14-day trial using the cloud application and I see the same problem there. When selecting dropdown list with multiple choice option active its response is [null]. It is possible you didn’t push the fix there? If any further information is required, please let me know. Thank you!

Can you let me know what version you are on, and that it’s 1.84.0 or later? By default, cloud will be on the latest stable version when you sign up, so I suspect that’s why you are not seeing the fix.

the latest stable version is 1.8.3 which is bugged, having null

This is solved in 1.84.0+ which will be marked as stable / latest in a few hours.
