Run script results in older SDK version

Hello all,

I may be facing a bug relating to Daml Studio (VS Code IDE) in the following case. I have installed Daml SDK versions 2.9.4 and 2.5.0. If I open a project for version 2.9.4 everything works as expected and I can run the script results. But if I don’t have that option available if I switch over to a project running on version 2.5.0.
On inspecting the logs for the IDE I get the following:

Invalid argument `multi-ide'

Usage: daml COMMAND

Available options:
  -h,--help                Show this help text

Available commands:

What can I do to resolve this issue (I’ve already tried opening VS Code via it’s own binary and via the daml studio command)?

Thank you, @David_Martins, for posting this.

As a workaround, I was able to display the script results by installing the 2.8.9 Daml VS Code Extension.

Not great, but it could get you unstuck if this is blocking work on a 2.5.0 project.

Edit: Be sure the “Auto Update” box in the Extension window is disabled.

Hello Wallace,

Did you change this project’s version to 2.8.9, or just the install?

I changed the Daml Extension version in VS Code. I did not change the SDK version in the daml.yaml file.

Thank you, this does unblock me as a workaround

This is related to the feature “Multi Package IDE Support” which can optionally be enabled in the Daml Extension settings. It is currently an “early access” feature.

@David_Martins disabling the “Multi Package IDE Support” is another workaround.

Here is a GitHub issue to track the issue.
