Daml Training Platform: Episode 5.2 Build Failure

I am working through Episode 5.2 and it was going well until I read the Monthly Developer email by @anthony. Up until that point I had been using Daml 1.13.1 with no SDK-related issues, just PEBKAC

I updated the system to the 1.14.xxxxx snapshot and resumed the tutorial. However now when I go to build the .dar from the existing private_nft/nft codebase I am getting a fatal build error. I thought that I’d shortcut it all and revert back to Daml 1.13.1, using daml install 1.13.1 --activate and daml uninstall 1.14.xxxxx however this has not fixed the issue.

$ make build

cd nft && daml build
Compiling nft to a DAR.

I have now done this three times completely using the make clean & make build commands to ensure that it is being done the same, everytime.

Hi @quidagis, what exactly do you mean by I updated the system to the 1.14.xxxxx snapshot and resumed the tutorial.? Did you actually change the daml.yaml of this specific project? Just installing an SDK version via daml install is not going to change a per-project SDK version unless you modify daml.yaml.

As for the error, there is a typo in your makefile. Line 3 should be

cd nft && daml codegen js -o daml.js ./.daml/dist/*.dar

i.e., ./.daml not ./daml.

I checked the daml.yaml and no, it was still set to 1.13.1 even after I installed the 1.14.1.xxxxx. Actually forgot about the daml.yaml anyway

. ← that’s all it took, thank you … PEBKAC strikes again.
