Hi @jsgaisie ,
The issue you were referencing here has been resolved, so I moved this to a new thread.
With the example you sent, though, there is an issue in that you are passing the value my text this isn't a valid API ID it would need to be something like my_text or, more specifically if it's in a Slice you'll need to pass it as something like slice.primary.my_text.
Can you tell me if you are querying this from a Slice or from a Static Zone? Is it a key text or rich text?
Thanks.
