The third argument to

?secret-key=${signingKey.directory}/secret&compression=zstdFor the

Passing just the list solves the problem.

&1a1008ea30The third argument to `open()` in `-|` mode is passed to a shell if it's a string. In my case the store URI contains `?secret-key=${signingKey.directory}/secret&compression=zstd` For the `nix store cat` case this means that * until `&` the process will be started in the background. This fails immediately because no path to cat is specified. * `compression=zstd` is a variable assignment * the `$path` argument to `store cat` is attempted to be executed as another command Passing just the list solves the problem.
