This error arises when the DAR you ran daml codegen js against is not known to the JSON API which in turn gets the list of packages from the participant and refreshes it automatically.

There are two common causes:

  1. The DAR did not get uploaded to the participant. Sounds like you checked that, so that shouldn’t be it.
  2. The generated JS code refers to an older version of a DAR. E.g., let’s say you build a DAR, run daml codegen js and then modify your Daml code and rebuild the DAR and upload that second DAR to the ledger. Your JS code will still refer to the old DAR which has not been uploaded to the ledger. In that case, make sure that you are regenerating your JS code whenever you rebuild your DAR.

You can get a list of packages known to the JSON API which might be useful for debugging by querying /v1/packages.
