Error when trying to run Daml Script against Daml Hub

Questions
1

I know there was a bug in Daml 2.3 but this should be something different because I’m using Daml 2.2. (I know that Daml 2.4 is already out which fixes the bug.)

I do everything as per the docs, still get this error:

Exception in thread "main" java.lang.IllegalArgumentException: Invalid host or port: https://he9859csro7wckhs.daml.app 443

The participants.json file contains the base data correctly:

   "default_participant": {
        "host": "https://he9859csro7wckhs.daml.app",
        "port": 443,

Am I doing something wrong?

Can you share the full error including stack trace and the full version number (e.g. 2.2.0)?

Sure, sdk-version: 2.2.0, the full error log:

Based on that it looks like you’re using JSON API parameters (in particular an HTTPS URL) rather but you have not passed --json-api to Daml Script. Either switch to the gRPC API (at least drop the https://, don’t remember if hub has different hosts and ports for that) or pass --json-api.

Passing this flag solves the problem, thank you!
