unexpected Content-Type when running installer.Install

[do87]

i keep getting:

unexpected Content-Type: "application/vnd+hashicorp.releases-api.v0+json"

as far as i can tell this issue started about 14-15 hrs ago, everything was working fine before.

when running:

installer := &releases.ExactVersion{
	Product:    product.Terraform,
	Version:    version.Must(version.NewVersion(TFVersion)),
	InstallDir: installDir,
}
execPath, err := installer.Install(ctx)
if err != nil {
	return err
}

tried with TFVersion = 1.1.9 and 1.1.7
i also tried with:

installer := &releases.LatestVersion{
	Product:    product.Terraform,
	InstallDir: installDir,
}
execPath, err := installer.Install(ctx)
if err != nil {
	return err
}

terrafrom-exec v0.16.0 (also upgraded to v.0.16.1 and still the same error)
go v1.18

Hi @do87
Thanks for the report and sorry for the trouble.
I believe this is a duplicate of #56 which was resolved in #57 (released earlier today as part of hc-install v0.3.2).

I noticed you filed the issue originally under terraform-exec, although that library is no longer responsible for installing Terraform. Can you clarify how do you consume hc-install? Is it a Terraform provider leveraging the plugin SDK?

If so, there's a PR currently pending review hashicorp/terraform-plugin-sdk#960 - once that is merged and released, providers should be able to continue running acceptance tests (which install Terraform using hc-install) once SDK is bumped to the latest version.

@radeksimko sorry, i didn't notice it belonged to hc-install, which is the package i am using to run the install. i'm following the example given in terraform-exec almost exactly, and the reason for my mistake is because i mainly use the tfexec functionality.

@do87 Were you able to upgrade to the latest hc-install and resolve the error?

go get github.com/hashicorp/hc-install@latest

[do87]

after updating to the latest version the install works again! thanks a lot 👍

Just to point out: requiring an upgrade will break the rebuilding of older versions of any provider. Would there be a backward compatible way of doing this change, so that older versions of providers can still be built? 🙇

[radeksimko]

@yannh That sounds like a question more for https://github.com/hashicorp/terraform-plugin-sdk This is repository for hc-install, which the SDK utilizes and the latest version of this library supports both old and new header name.

I imagine one option would be getting the API to return the old header and the other would be backporting this patch somehow. I believe the older version of hc-install which the SDK uses (tfinstall) doesn't perform such strict header checking, so some older provider versions using SDK which relies on tfinstall may not have this problem.

Either way I would suggest opening an issue in the SDK repository and describe what versions of the SDK you were hoping to continue using. I can't promise anything - especially because I don't maintain the SDK - a different team does - but it is worth asking! 😄
