The text appearing in the "Value" window doesn't look like well formed JSON. It looks like it is a paste inside a previous paste. If you want "feature" inside the window, it should be in quotes as should "attributes" along with some commas in there. I would also suspect that the Name should be "features" not "updates". I must admit, however, that I am not very familiar with Integromat. To check your JSON, try jsonlint.
