Error: Cannot read property "_meta" from null

[DamienT]

Hi everyone,

I'm new to the forums and to service now so go easy!

I'm creating a flow behind a catalogue item which creates a ticket in a queue and then calls a subflow which generates a pdf document of the request. The subflow is very basic - it receives a sys is for a ticket, verifies that the ticket exists, generates a pdf via the API, then attaches the pdf to the ticket.

However I'm running into this error when the subflow runs:

Error: Cannot read property "_meta" from null,Detail: Cannot read property "_meta" from null

The logs seem to hint that the error is with the script, however I don't know where to begin troubleshooting this as the script doesn't include any variables called _meta.

Could anyone give me some hints or insight? 

Cheers!

@DamienT 

it clearly looks like input is not passed to that subflow and hence the error

Hi @DamienT 

Check you script here.  A script in flow or a Flow Designer action is attempting to access metadata or internal tracking data from an object, a record, or an API payload that is completely empty.
