   The error log seems maybe there is a bug at: https://github.com/yangxikun/opentelemetry-lua/blob/6c4a5112de5f70bb94a87e39656121f9c7407d95/lib/opentelemetry/trace/batch_span_processor.lua#L37
   
   Could you try replace `/usr/local/apisix/deps/share/lua/5.1/opentelemetry/trace/batch_span_processor.lua#L37` to:
   ```lua
   if now() - self.first_queue_t >= self.batch_timeout and #self.queue > 0 then
   ```
   then restart apisix container and test if the error log still appear.
   
   BTW, the above bug shouldn't affect sending spans. Does your otel-collecotor 4317 port use http protocol? otel-collector-config.yaml just like:
   ```yaml
   receivers:
     otlp:
       protocols:
         http:
           endpoint: 0.0.0.0:4317
   ```
