What causes "error finding remote workspace: %w" in opentofu/opentofu?

Verify the workspace still exists and the token can read it (same checks as the 'workspace not found' error, backend.go:1126).

error finding remote workspace: %w

Error message

error finding remote workspace: %w

What it means

Appended by Cloud.LocalRun (internal/cloud/backend_context.go:109) when b.getRemoteWorkspaceID fails while resolving the opaque workspace ID needed to list workspace variables (only on the non-AllowUnsetVariables path). getRemoteWorkspaceID performs a Workspaces.Read, so this wraps the same failures as fetchWorkspace: 404 (missing workspace or invisible to token), auth, network.

Solutions

Verify the workspace still exists and the token can read it (same checks as the 'workspace not found' error, backend.go:1126).
Re-run; transient mid-run 404s from eventual consistency usually clear.
Correct workspace selection (tags mapping, TF_WORKSPACE) before planning.

Defensive patterns

Strategy: type-guard

Validate before calling

// Confirm workspace resolvable before LocalRun's variable phase
if _, err := client.Workspaces.Read(ctx, org, op.Workspace); err != nil {
    return fmt.Errorf("workspace %s unreadable (%w) - fix name/token first", op.Workspace, err)
}

Type guard

func isRemoteWorkspaceLookupFailure(err error) bool {
    return strings.HasPrefix(err.Error(), "error finding remote workspace")
}

Try / catch

_, _, diags := b.LocalRun(ctx, stopCtx, op)
if isRemoteWorkspaceLookupFailure(diags.Err()) {
    // wrapped cause is a fetchWorkspace-style error: 404 vs auth vs network decides the fix
}

Prevention

Validate TF_WORKSPACE and tag mapping in a pre-flight step of pipelines.
Avoid deleting/renaming workspaces while pipelines may be mid-run; use tombstone workspaces instead.
Reuse the same identity checks as fetchWorkspace errors (team membership, org spelling).

When it happens

Trigger: Workspaces.Read during variable resolution returns tfe.ErrResourceNotFound, 401/403, or transport errors - e.g. workspace deleted between the earlier StateMgr step and here, or token without read access to that workspace.

Common situations: Workspace renamed/deleted mid-pipeline; wrong TF_WORKSPACE for the mapped environment; token team removed from the workspace between runs.
