Fix deploy github action

[gavriliumircea]

Right now the "Merkle API Deployment on Vercel" github action cannot be used. This seems to be related to a mismatch between the rust build target and the linux image created by vercel. Before trying to run the action it is mandatory to recreate .cargo/config.toml file (https://github.com/vercel-community/rust#prebuilt-deployments). Before trying to a fix check the list bellow that contains a series of commits with "failed fixes attempts":

Am I right that this is because vercel build does not allow us to pass custom compilation options, and so we need to resort to the configuration file approach?

[gavriliumircea]

It seems like it but the vercel team doesn't really offer a proper explanation or an alternative for that config file.

[PaulRBerg]

Yes, it seems like it. I asked them yesterday why there's that requirement:
