Version Information

Server Version: v2.0.10
CLI Version (for CLI related issue):

[nix-shell:~/dev/cuddlefish/hasura]$ hasura version
INFO hasura cli                                    version=dev
INFO hasura graphql engine                         endpoint="http://localhost:8080/" version=v2.0.10

I'm running the hasura-cli package in nixpkgs as of commit https://github.com/NixOS/nixpkgs/commit/c11d08f02390aab49e7c22e6d0ea9b176394d961.

Environment

macOS 12.0.1 running on aarch64-darwin (aka M1).

What is the expected behaviour?

hasura console to work, with metadata/migration changes made in the console to update the files in the metadata/ and migrations/ directories.

Keywords

hasura cli, cli-ext, M1, arm64, aarch64, aarch64-darwin, nix, nixpkgs, hasura-cli, arm

What is the current behaviour?

When making edits in the console that ought produce changes in metadata/ or migrations/:

[nix-shell:~/dev/cuddlefish/hasura]$ ./console.dev.sh 
INFO console running at: http://localhost:9695/   
WARN Unable to find an embedded cli-ext. So trying to fetch it from CDN 
WARN Tip: --cli-ext-path can be used for setting up cli-ext from local file system 
WARN Unable to find an embedded cli-ext. So trying to fetch it from CDN 
WARN Tip: --cli-ext-path can be used for setting up cli-ext from local file system 
WARN Unable to find an embedded cli-ext. So trying to fetch it from CDN 

And when I attempt to install the cli-ext plugin manually:

[nix-shell:~/dev/cuddlefish/hasura]$ hasura plugins install cli-ext
FATA[0001] failed to install plugin "cli-ext": plugin "cli-ext" does not offer installation for this platform 

How to reproduce the issue?

Follow either of the steps in the previous described in the "current behavior" section.

no interesting logs are generated besides the ones presented above

Any possible solutions?

None AFAICT

Can you identify the location in the source code where the problem exists?

no

If the bug is confirmed, would you be willing to submit a PR?

AFAIU Fixing this requires buy-in and investment from hasura to officially support ARM platforms.

Begin with the CLI extension installation path exercised by hasura plugins install cli-ext and the fallback shown by console.dev.sh on aarch64-darwin; the issue names no source files or tests. Done means cli-ext installs on Apple Silicon and hasura console persists metadata and migration changes without the platform error.
