I’m trying to transform

I’ve tried the Item List and Set Nodes, but I keep up ending up with the extra “attachments”: [
{ bit …

[
{
"attachments": [
{
"type": "attachment",
"content": {
"type": "Buffer",
"data": [
137,
80,

Any suggestions on how to solve this will be really appreciated!

Thanks in advance.

Hi @dickhoning - when I try to do this with Item Lists node, it works when “Include: No Other Fields”. The attachments: key is only added when “All other fields” or “Selected other fields” is selected for the “Include” parameter.

Here is an example - the function node is simply outputting your same data (except for the headers info):

Hi @maxT thanks, and in the meantime I already found another solution. Apparently, there is more than one road to Rome :grinning:
