What can cause a '404 Not Found' error when I try to run an init script against an app deployed on Daml Hub?

Questions Features & Bugs

The script works against Sandbox running with the same app. The first create command of the script which causes the error works when I issue it with Postman.

The error message is rather cryptic:

Exception in thread "main" com.daml.lf.engine.script.ScriptF$FailedCmd: Command submit failed: Request to /v1/create with Some(<request body>) failed with status 404 Not Found: List()
Daml stacktrace:

Can you show your participants.json (without the tokens)? It looks like the url might be off.

It’s like this:

{
  "default_participant": {
    "host": "https://api.projectdabl.com",
    "port": 443,
    "access_token": "xxx"
  },
  "participants": {
    "gyorgy_rtledgers_com": {
      "host": "https://api.projectdabl.com",
      "port": 443,
      "access_token": "xxx"
    }, etc.

This is not working either:

https://api.projectdabl.com:443/v1/create

Try replacing https://api.projectdabl.com with https://yourledgeridhere.daml.app. You can find the ledger id in your ledger settings in the hub console.

This works:

"default_participant": {
    "host": "https://cxs7h3enaoiaaehw.daml.app",
    "port": 443,
    "access_token": "xxx"
  },
  "participants": {
    "gyorgy_rtledgers_com": {
      "host": "https://cxs7h3enaoiaaehw.daml.app",
      "port": 443,
      "access_token": "xxx"
    }, etc.

Why isn’t this in the exported json?

Definitely a bug, we’ll make sure to fix it.
