+:::{dropdown} Error when using the Opentelemetry onboarding flow using EDOT Collector
+Applies to: {{stack}} 9.1.6, 9.2.0
+
+**Details**
+
+Users trying to collect logs and host metrics using the Elastic distribution of the OTel collector will see error when using the OpenTelemetry quickstart onboarding flow:
+
+```
+> sudo ./otelcol --config otel.yml
+
+Starting in otel mode
+failed to get config: cannot unmarshal the configuration: decoding failed due to the following error(s):
+
+'exporters' error reading configuration for "otlp/ingest": decoding failed due to the following error(s):
+
+'sending_queue' decoding failed due to the following error(s):
+
+'batch' decoding failed due to the following error(s):
+
+'' has invalid keys: flush_interval
+
+```
+
+**Workaround**
+
+To work around this issue, manually update the configuration of the generated `otel.yaml` file to replace incorrect key `flush_interval` with the correct key `flush_timeout`.
+
+```yaml
+batch:
+  flush_timeout: 1s
+```
