Deployment creation fails with no usable error

[matt-fff]

Today updating and creating deployments suddenly stopped working.

 +  vercel:index:Deployment test-deployment creating (0s)

 +  vercel:index:Deployment test-deployment **creating failed** error: Error creating deployment: Could not create deployment, unexpected error:  - 
    pulumi:pulumi:Stack storefront-test2 running error: update failed

The error is nondescript; when you dig deeper, it turns out to be unknown errors that Pulumi doesn't know how to represent.

I0116 18:48:57.522937 1586969 provider_plugin.go:2128] provider received rpc error `Unknown`: `Error creating deployment: Could not create deployment, unexpected error:  - `

Here's the Pulumi code that generates that error: https://github.com/pulumi/pulumi/blob/9962fede181431da693315f13b1f806a5bd44435/sdk/go/common/resource/plugin/provider_plugin.go#L2132

Here's a minimal version of the project I used to generate the error:

from dotenv import load_dotenv
import pulumi
import pulumiverse_vercel as vercel
import os

load_dotenv()

team_id = os.environ["VERCEL_TEAM_ID"]

vercel_project = vercel.Project(
    "test-project",
    team_id=team_id,
    framework="sveltekit-1",
    serverless_function_region="sfo1",  # Set the region to San Francisco, close to Supabase DB
)

site_path = "../"

# Get project files
project_files = vercel.get_project_directory(site_path)


# Add a Vercel deployment
vercel_deployment = vercel.Deployment(
    "test-deployment",
    team_id=team_id,
    project_id=vercel_project.id,
    files=project_files.files,
    path_prefix=site_path,
    production=True,
)

pulumi.export("vercel_deployment_url", vercel_deployment.url)

^ This was working as expected yesterday.

Seems likely this issue is upstream: vercel/terraform-provider-vercel#259

Hi, @matt-fff - this was indeed an upstream issue. There was a regression in the Deployments API. It should be fully resolved now!
