@j-chao thanks for reporting this, this is an upstream issue we're looking into.

[j-chao]

@tombuildsstuff just curious, what's the upstream issue?

[tombuildsstuff]

@j-chao internal upstream, not upstream-upstream - sorry - we're missing a Content-Type when sending this request for some reason (which is a bug) but appears to be a breaking behavioural change in the API, since this has been fine historically

[tombuildsstuff]

Fixed via #14927

[github-actions]

This functionality has been released in v2.92.0 of the Terraform Provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.

• Installing hashicorp/azurerm v2.92.0...
• Installed hashicorp/azurerm v2.92.0 (signed by HashiCorp)

[...]
Terraform has been successfully initialized!
