The way to get access token from Adobe IO

Hi everyone. I'm facing an issue when trying to get an access token in order to insert data into the adobe campaign

I've been trying to use a solution from https://adobe-consulting-services.github.io/acs-aem-commons/features/adobe-io-apis/index.html to generate the access token automatically and can not get the access token.

Here's my configuration:

And Here's the status from the health check

Does anyone know where is my incorrect?

Btw, Could you guys please suggest to me any solution that can generate the access token and jwt token automatically, I very much appreciate you

Thanks so much!
