Cannot deploy - .next-tf/lambdas\__NEXT_PAGE_LAMBDA_0.zip: no such file or directory

[C0D3-BL00D3D]

I'm trying to deploy using Terraform Cloud (just discovered Windows isn't supported) but I'm getting this error:

Error: Error in function call

on .terraform/modules/tf_next/main.tf line 67, in resource "aws_lambda_function" "this":
67: source_code_hash = filebase64sha256("${local.config_dir}/${lookup(each.value, "filename", "")}")
├────────────────
│ while calling filebase64sha256(path)
│ each.value is object with 4 attributes
│ local.config_dir is "./.next-tf"

Call to function "filebase64sha256" failed: open
.next-tf/lambdas\__NEXT_PAGE_LAMBDA_0.zip: no such file or directory.

The .next-tf folder is in the root of my project, and its lambdas subfolder does have __NEXT_PAGE_LAMBDA_0.zip.

I get this error whether I include !**/.next-tf/** in my .terraformignore or not.

The README says I should “upload the build output from the tf-next task”, but this instruction is unclear to me. I don't see where I can upload anything on Terraform Cloud.

I'm not using basePath, but I am using baseUrl, not sure if this matters.

Any guidance would be appreciated.

Local: Terraform v1.3.4 on windows_amd64
Terraform Cloud: Terraform v1.3.4 on linux_amd64
tf-next: ^0.13.2

filename for __NEXT_PAGE_LAMBDA_0 in .next-tf/lambdas/config.json was "lambdas\__NEXT_PAGE_LAMBDA_0.zip". The \ was causing the issue.

Manually changing filename to "lambdas/__NEXT_PAGE_LAMBDA_0.zip" fixed it.
