Failed to fetch list of base images

Error message

Failed to fetch list of base images

What it means

Reported by report_fatal_error inside prompt_for_docker_image — the image fetch performed when `warp environment create` runs without --docker-image. The GraphQL request transport succeeded but response.list_warp_dev_images came back as UserFacingError or Unknown instead of ListWarpDevImagesOutput, so there is no image list to prompt with. Structurally identical to error 101 but on the create path.

Solutions

1. Log in / refresh credentials and retry
2. Pass --docker-image to skip the fetch entirely and create directly
3. Update the Warp client to eliminate schema/enum Unknown mismatches
4. For local server setups, verify the endpoint and that listWarpDevImages is served

Example fix

# before
warp environment create --name dev --repo owner/repo

# after
warp environment create --name dev --repo owner/repo --docker-image warpdotdev/base:latest

// Verify auth + catalog before an interactive create:
// warp environment image list || echo "catalog unavailable — pass --docker-image"

match response.list_warp_dev_images {
    ListWarpDevImagesResult::ListWarpDevImagesOutput(output) => { /* prompt with output.images */ },
    ListWarpDevImagesResult::UserFacingError(e) | ListWarpDevImagesResult::Unknown => { /* retry or fall back to --docker-image */ },
}

When it happens

Trigger: Creating an environment without --docker-image while logged out, with an expired token, against a server that returns a user-facing error for listWarpDevImages, or with a client whose generated GraphQL enums cannot decode a newer server response (Unknown variant).

Common situations: Logged-out token expiry between commands; version skew between old client and new server API; local warp-server without the resolver; server-side incident returning error payloads.
