Can't create a new project (PR #73)

[r03ert0]

In PR #73 (@dhovart)

I'm using the code with NWL components from https://microdraw.connect-project.io/

Observed:
I created a new project, and added 3 files: https://microdraw.pasteur.fr/F2417_transmittance/F2417_transmittance.json, https://microdraw.pasteur.fr/F2417_retardance/F2417_retardance.json, https://microdraw.pasteur.fr/F2417_orientation_hsv/F2417_orientation_hsv.json. I set the annotation to vectorial, and named it. Clicking "Save Changes" doesn't produce any feedback, and the project is not saved. No errors are displayed in the Web Console.

Expected:
A feedback should be provided indicating that the project was successfully created, or providing an error message indicating why the project couldn't be saved.

There was a small error in a condition
This should be fixed.
