Issue with JSON structure/syntax

[Takshak]

My JSON contains data, appears to be correct, however when I am trying to use it using javascript, it is simply returning [object object] istead of real data which is causing systax error while loading it into MongoDB through API.

Please refer to the screenshot:

What is the error message (if any)?

400 - “"Invalid syntax error: TypeError: invalid character ‘o’ looking for beginning of value"”

This solved the problem.

Expression returning [object Object]

I have the same issue. I want to add the json data from the previous node, but if I just use $json it doesn’t work out… The next node tells me it’s not valid json [image] This is how the expression evaluates in my Set parameter with expression. [image]

Thanks!
