Upload a file to Fireflies by using Fireflies - Execute a GraphQL module - getting an error

Hi all,

I’m trying to upload an audio file from my Google drive into Fireflies to do a transcript. To perform these I use a Fireflies module called Execute a GraphQL an a few lines of JSON. How it looks like:

Here is the screenshot of the module’s settings:

I’ve tried all possible option with For or Collection in Variables data source, different version of code - but it doesn’t work.
I’m getting different errors like this:

Or like this:

Here is the dump of the Fireflies:
Fireflies - Output dump.txt (2.2 KB)
And here is scenarion itself:
blueprint (14).json (28.9 KB)

In other scenarios I use Execute a GraphQL module for download an audio or delete a record and everything works perfectly - but in those scenarios there is one variable which is transcribe ID - here is two.
I also tried to do the same by using HTTP module but always getting Error: 500 Internal Server Error

Read Fireflies API and other following documentation - seems it should work.

Could someone, please, help me to validate settings in GraphQL module and advise what I do wrong?
