Describe the problem/error/question

What is the error message (if any)?

I am getting this duplicate key error and I have no idea how to fix this. I tried an output parser but that did not work properly.

Hi @Anthony_Chet,

Could you provide a screenshot of the Salesforce node options?

If you’re comfortable sharing the workflow as well, that would be really helpful!

[Anthony_Chet]

Hey thanks I actually solved it. appreciate the support

[gabrielstoco]

What did you do? I have the same error here

[Anthony_Chet]

You have to define it as an expression not fixed. I used chatgpt to help me

[gabrielstoco]

Hmmm, I see. Thank you!

[Anthony_Chet]

are you also using salesforce

[gabrielstoco]

Not really. I had the same problem with both the postgres node tool and the subworkflow node tool. I saw here in a githhub issue that it is a bug and will be fixed in the next update.
