Hello all,
Implement what I understand is now an outdated ex-cdm-swaps module but getting errors that the dar file is
Error: Invalid dar file: CdmSwaps-1.0.0.dar
Running on Centos 7 Google Cloud VM Instance
The repository example is here
It is for my financial engineering and I need the platform running in hours. I will appreciate any help
Could the conflict be with the newer sdk installed against the one the example references.
How can i roll the sdk back to the appropriate one.
Thanks
Best Regards,

As long as you haven’t change the sdk-version in the daml.yaml things should still work.
At which step are you getting the error? The readme tells you to run daml sandbox .daml/dist/CdmSwaps-1.0.0.dar. It looks like you might be running daml sandbox CdmSwaps-1.0.0.dar without the proper path or you have forgotten the daml build step before that.
Thanks Moritz for coming in.
I did the daml build and the sbt compile before that.
I did the right path.
I got the error at the daml sandbox .daml/dist/CdmSwaps-1.0.0.dar step
Thanks
Best Regards,

I’ve just cloned the repository and tried daml build followed by daml sandbox .daml/dist/CdmSwaps-1.0.0.dar and it seems to work for me. Are you sure you did not modify the daml.yaml file?
What output do you get from daml build? You should be getting something like
Compiling CdmSwaps to a DAR.
Created .daml/dist/CdmSwaps-1.0.0.dar.
Hello Moritz,
I did not change the yaml file
Could i run the build commands again.
I remember i had a warning with sbt compile stage .Here…

The sbt compile step doesn’t matter. If sandbox is throwing an error I need to see the full output of the daml build step and of the daml sandbox .daml/dist/CdmSwaps-1.0.0.dar step.
Here is it Moritz,
[olusegun_oluwajebe_wqu@group22 app]$ daml sandbox .daml/dist/CdmSwaps-1.0.0.dar
DAML SDK 1.0.1 has been released!
See https://github.com/digital-asset/daml/releases/tag/v1.0.1 for details.

Can you please also show us the output of daml build.
Here Moritz,

Hm that looks fine. Can you run ls -l .daml/dist from the same directory where you are running daml sandbox from?
I got this,
[olusegun_oluwajebe_wqu@group22 app]$ ls -l .daml/dist
ls: cannot access .daml/dist: No such file or directory
Are you sure you are running daml build and daml sandbox frm the same directory? daml build will create .daml/dist. If you cannot find it with ls it sounds like you might be in a different directory. You should run both commands from the root directory of the project.

am i supposed to run the saml build from the app folder?
No you should run daml build as well as daml sandbox from the root directory, i.e., the one with the daml.yaml in it. The only command that you should run from app is sbt compile.
I just ran it from the project folder:
olusegun_oluwajebe_wqu@group22 ex-cdm-swaps]$ daml sandbox .daml/dist/CdmSwaps-1.0.0.dar

That looks right! So is everything working properly now or do you have other issues?
Thanks.
I need to follow the other steps. I will get back.
This is wonderful support.
I really appreciate your kindness

That looks like you are just running out of memory. How much RAM do you have?
