JSON Parser Step Error - Flow Designer

[Rachna S]

Hi,

How do I use JSON parser step in flow designer along with 'REST' response saved as attachment ?

So I am making a Get REST call and saving the JSON response as a .txt attachment in servicenow. I'd like to use JSON parser step after this to parse response saved in the attachment. I'm looking up for the attachment and passing it to JSON parser step. However, it throws an error stating this 'JsonParserOperation failed: Extraction of Complex Object failed: JsonStreamParser[0]: JSON must be an object or an array: '4' com.glide.transform.transformer.exceptions.InvalidStructureException'

Please advise.

Hi Ankur,

I know how both the steps work. I am able to use them if I do not save REST step's response as attachment. However, when I save it as attachment and pass the attachment to JSON Parser step, it throws error.

Hi Ankur,

I've figured this out. It threw error only when I used MID server to make a REST call. Thank you though.
