Hey, I’m going to collect data from the particular url by using tavily and record in Monday.com.
I tried everything I can do but “Cannot read properties of undefined (reading ‘content’)” this error keeps popping up.
Hey,
I think because it has different chars, maybe using stringify() will help it,
{{ JSON.stringify($json.content) }}
Hopefully fixes the issue,
Best regards,
Samuel
Thank you for your help
I just tried but it didn’t work…
@Jeongmin_Seo your welcome, am wondering if it’s because of is it Chinese text? Do you get same issue with company instead of content? It seems the issue is the simple memory, do you need memory on the ai agent, you can try with postgres as memory for agent or without it? Do you get same error then?
Samuel
Hm okay see unrelated to the content, can u save workflow, and restart server, otherwise maybe have to look into config, not 100 percent sure why, but maybe help.
Samuel
still not working… thank you for your help!
Maybe disconnect the memory for now and try again.
From the screenshot the contect seems fine.
We can not enter to your workflow so maybe you can copy the workflow code and paste here
between the
paste here
I don’t know how to upload my JSON file so I will just copy and paste the file below.
Thank you so much for your help.

Try and reference the code node by name like this:
{{ $('Code').first().json.content }}
The error suggests that $json is undefined for some reason, even though it holds a value
Are you saying that copy that code into the AI Agent prompt?
I modify the code node a bit.
Please try this version will work or not
Because the original version working too on my end. So it’s quite weird.
Did you execute from the begining of the trigger?
It is not working…
Wait so in your workflow, when you add new item in your Monday.com, does this workflow automatically fill the employment count column?
Thank you for your help
