1C + Trello - use sample project but it seems doesn't work

Hi, I downloaded *.cf file here (example 1C with Trello integration)
then, I receive API key for my Trello workspace - I can collect it only after building a power-app. So I've built it, add this power app om by board even )) then run your configuration, add API key and secret to constants,
press button "Refresh" but nothing happens

Did you test?

Hello Alex,

of course, all these applications were checked before publication. The application you are writing about was tested by me personally. To understand what is not working for you, you need to see what error Trello returns to you at the moment when you click the "Refresh" button.

Have you tried watching debugging?

Hey Alex,

did you manage to make an example with Trello?
