Current Behavior

Allcoder templates push commands fail with "Error: No configuration files" when using Coder v2.26.0+ control plane. This affects:

• Custom templates that previously worked on v2.25.x
• Fresh templates generated bycoder templates init
• All upload methods:-d flag, stdin tar, and direct push from template directory

2025-10-08 13:06:19.465-04:00 Terraform 1.13.02025-10-08 13:06:19.465-04:00 Error: No configuration files2025-10-08 13:06:19.465-04:00 Plan requires configuration to be present. Planning without a configuration would mark everything for destruction, which is normally not what is desired. If you would like to destroy everything, run plan with the -destroy option. Otherwise, create a Terraform configuration file (.tf file) and try again.

TL;DR: Something about Terraform 1.13.0's integration with Coder's file extraction/placement mechanism appears broken. The server-side Terraform cannot locate uploaded .tf files in its working directory during the "Detecting persistent resources" phase.

Expected Behavior

coder templates push should upload files properly, should not warn about resource destruction

Templates should push successfully as they did on Coder v2.25.0 with Terraform 1.12.x.

Steps to Reproduce

1. Upgrade Coder control plane from v2.25.x to either v2.26.x or v2.27.0
2. Generate a minimal template:coder templates init --id scratch /tmp/test
3. Push the template:cd /tmp/test && coder templates push test-minimal -y
4. Observe "Error: No configuration files" from Terraform 1.13.0

OR

1. Upgrade Coder control plane from v2.25.x to either v2.26.x or v2.27.0
2. Use any existing template (with main.tf present and validated)
3. Attemptcoder templates push <name> -d <directory> -y
4. Same error occurs

Environment

• Host OS: macOS Darwin 24.6.0 (darwin_arm64) - client; Ubuntu 24.04.2 LTS (linux_arm64) - server
• Coder version:
  • Control plane: v2.27.0+c0cd32c (originally affected upgrade from v2.25.x -> 2.26.0)
  • CLI: v2.27.0+c0cd32c

Additional Context

The issue occurs consistently, The issue is new (previously worked fine), I have tested this on the latest version
