Error message

openfgaError.Error()

What it means

Returned by the OpenFGA write path when the underlying OpenFGA client returns an error that unwraps to an InternalError; it is re-exposed as TooManyRequests because writes are commonly rejected under load/quota. The message is the OpenFGA error's own text (openfgaError.Error()).

Solutions

1. Check OpenFGA container health/logs and restart it if it is crash-looping or overloaded
2. Reduce write concurrency / batch tuple writes to stay under OpenFGA limits
3. Verify network connectivity and OPENFGA_API_URL/creds between the service and OpenFGA
4. Retry with backoff — this error type is transient in nature

err := server.Write(ctx, req)
if err != nil {
    if errors.Is(err, errors.CodeTooManyRequests) {
        // exponential backoff + jitter, honor Retry-After if present
        return retryWithBackoff(func() error { return server.Write(ctx, req) })
    }
    return err
}

When it happens

Trigger: Calling Write (tuples write/delete/check) against OpenFGA when the server returns an internal error — often rate limiting, connection limits, or store overload surfaced as InternalError.

Common situations: OpenFGA container resource-starved or restarting; too many concurrent writes from telemetry pipeline; OpenFGA version where rate limits map to InternalError; network issues between query-service and OpenFGA.
