Hi all, I am currently trying to host the daml finacne app on daml hub but I am running into some problems. When uploading the dar files it gives me the following error: Error installing artifact: Error installing artifact: LF V1.15 unsupported. I hope someone can help me on that. Here is a link for the Daml Finance App github for reference: > **[GitHub - digital-asset/daml-finance-app](https://github.com/digital-asset/daml-finance-app)** > > Contribute to digital-asset/daml-finance-app development by creating an account on GitHub.

Daml-LF 1.15 is still only a preview in SDK 2.4. Unfortunately you cannot use preview versions on Daml Hub. ---

Thank you! The only reason why I wanted to deploy it to the hub was because I was able to run it smoothly on mac, however when I try to run it on windows, after the commands: ./script/get-dependencies.sh daml start I got the following error: Passthrough is not supported, GL is disabled, ANGLE is Do you know why that is? ---

You mention running `get-dependencies.sh` - are you running this in WSL? When running `get-dependencies.bat` (ie. the Windows script) I realized that it’s outdated in that it doesn’t download the right dependencies. I’ll look into fixing this. Could you post the full logs from `daml start` so that I can better understand the context of the error? EDIT: [Fix get-dependencies.bat by GeorgSchneider · Pull Request #50 · digital-asset/daml-finance-app · GitHub](https://github.com/digital-asset/daml-finance-app/pull/50) should fix the `get-dependencies.bat` script. ---

Hi Georg, unfortunately I couldnt replicate the error to get you the complete log. I was running on the regular terminal without WSL. On the Readme the linux/mac and windows instructions are the same. Nonetheless, I will try the fix you provided. Thank you! ---

Indeed, the readme does contain wrong instructions for Windows. Fixing this now. Pull the latest from `main` and run: ```haskell ./script/get-dependencies.bat daml start ``` (note the different file ending `.bat`) ---

Yes, that fixed the issue for the dependencies! However, once I run daml start I get this: ![image](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/3/3833e995ab7f8953495643a83b9c11c8747d055f.png) ---

Can you paste the contents of the `.lib` directory? Maybe there was an error downloading this file. ---

This is the contents of .lib ![C0CDC2AE-4107-4E2D-9C20-D4FC2D3B0B6C](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/4/43c0d4b5a1e064c201cac5f3d984c979f3fa33ab.jpeg) ---

So that package is indeed missing. But it’s referenced in `get-dependencies.bat` here: [daml-finance-app/get-dependencies.bat at 0f322d5b67c498dd40a96f9e603244c47eb05efe · digital-asset/daml-finance-app · GitHub](https://github.com/digital-asset/daml-finance-app/blob/0f322d5b67c498dd40a96f9e603244c47eb05efe/script/get-dependencies.bat#L25) Can you post the logs from `get-dependencies.bat` after cleaning out `.lib/`? ---

Hi Georg, I’m trying a different approach. I’m now trying to start the application in a linux vm The get-dependencies is working fine, however, when I execute daml start I get the following message: ![433A5C62-AA77-4015-BE77-D526594A9864](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/7/7487d19227e345000347a5846815af3e425858fa.jpeg) ---

That is odd - could it be that the VM is sized too small for Canton to run? I’d suggest at least 8gb memory and a decent CPU. On your previous attempt on Windows, could you post the logs from `get-dependencies.bat` after cleaning out `.lib/`? I think you’re missing just that one dependency, which I suspect failed to download for some reason. ---

Hi Georg, Fortunately I could fix the issue regarding the get-dependencies. Unfortunately I dont have access to the environment I was trying to run it previously to send you the previous logs. I encountered a different error running locally on a Mac machine. I just cloned the repository again so I can get the updated version of the application, however, when I try the command “daml start” I get the following error: ![A15F715C-C20B-4129-BCAD-2B23B7A4770D](https://canada1.discourse-cdn.com/flex028/uploads/daml/original/2X/d/d0f1868fbfc01a11aaaa8efa3dcda30754e5f7b3.jpeg) ps: It was working fine before getting the new version… Thanks ---

This is an issue with one of our scenarios when you run it on the 31st of a month 🙂 we’ll look into fixing it, but it should work if you run it on any other day (eg. today). Let me know in case you’re still encountering issues. ---

Hi Georg, Thank you for your support. Everything is working fine now I was able to fix the grpc error by upgrading the memory of the ec2. I’ve changed it from a t2.medium 8gb to a t2.xlarge 16gb and it fixed the issue
