Hello everyone,
I used to have a simple shell.nix on a project that I only occasionally play with. I have done updates to this project using terraform from my nixos before ( last occurence 0ct 27 this year )
with import <nixpkgs> {config.allowUnfree=true;};
mkShell {
name = "nix dev env";
packages = [
terraform
kubernetes-helm
msmtp
bind.dnsutils
k9s
];
}
So a vanilla terraform really. yestrday I wanted to push a small fix and I got
│ - Failed to obtain provider schema: Could not load the schema for provider registry.terraform.io/hashicorp/null: failed to instantiate provider "registry.terraform.io/hashicorp/null" to obtain schema:

│ This usually means

I tried removing the .terraform directory and running init again but got another error this time :
╷
│ Error: Failed to install provider
│
│ Error while installing hashicorp/null v3.2.2: failed to open temporary file to download from https://releases.hashicorp.com/terraform-provider-null/3.2.2/terraform-provider-null_3.2.2_linux_amd64.zip: open
│ /tmp/nix-shell-123481-0/terraform-provider3862495864: no such file or directory
looking around, I notice that there are terraform-providers for all the plugins I use. I try to replace my naive terraform import and use terraform.withPlugins instead
with import <nixpkgs> {config.allowUnfree=true;};
mkShell {
name = "nix dev env";
packages = [
(
terraform.withPlugins(p:[
p.null
])
)
kubernetes-helm
msmtp
bind.dnsutils
k9s
];
}
I drop both .terraform and the .terraform.lock.hcl then run init again.
To no avail but with a different error this time.

running .terraform/providers/registry.terraform.io/hashicorp/null/3.2.3/linux_amd64/terraform-provider-null_3.2.3 directly yields
This binary is a plugin. These are not meant to be executed directly.
Please execute the program that consumes these plugins, which will
load any plugins automatically
which seems to point that it does and can run
I’m a bit at a loss as to how I can fix my install at this point. I don’t really care if the plugins versions have changed and introduced incompatibilities with my tf files. They are small and I don’t use fancy plugins so fixing the issues shouldn’t be a problem, but I can’t run anything for now 
the only “major” change I did recently is upgrading to 24.11
I further tried to use the terraform package from unstable but it fared no better.
What am I doing wrong ?
