What causes "error loading workspace: %w" in hashicorp/terraform?

Treat the inner error like 484/485: check workspace name/access (404) or auth/network (other).

error loading workspace: %w

Error message

error loading workspace: %w

What it means

In FetchVariables (backend_context.go:194-198), after getRemoteWorkspaceID succeeded, a SECOND workspace fetch via b.fetchWorkspace(ctx, b.Organization, workspace) failed. Note getRemoteWorkspaceID already read the workspace; this duplicate read can fail independently (e.g. race, or a 404/permissions path that fetchWorkspace re-wraps with the verbose 'workspace not found' message).

Solutions

Treat the inner error like 484/485: check workspace name/access (404) or auth/network (other).
Retry; if it was a transient race the second read may succeed.
Verify the token's permissions haven't changed during the operation.
Ensure no concurrent workspace rename/delete is happening.

Defensive patterns

Strategy: retry

Try / catch

// Re-fetch workspace once on transient failure during variable load.
w, err := b.fetchWorkspace(ctx, org, ws)
if err != nil && isTransient(err) {
    time.Sleep(backoff); w, err = b.fetchWorkspace(ctx, org, ws)
}

Prevention

Avoid concurrent rename/delete of the workspace during runs.
Ensure permissions are stable across the operation lifecycle.
Retry transient mid-operation workspace read failures.

When it happens

Trigger: b.fetchWorkspace at backend_context.go:194 returns an error. Because fetchWorkspace (backend.go:1328) maps ErrResourceNotFound to the verbose 484-style message and everything else to the 485-style message, this surfaces one of those wrapped forms inside 'error loading workspace'.

Common situations: Transient inconsistency or race where the workspace became inaccessible between the two reads. Permissions changed mid-operation. The same root causes as errors 484/485 (name/access/auth/network) but manifest during variable loading specifically.
