**Versions** (relevant - OpenSearch/Dashboard/Server OS/Browser): Opensearch Dashboard 2.14

**Describe the issue** :  
I am gathering metrics data from OTEL, which is then ingested into DataPrepper. I use the following Metric Pipeline in DataPrepper to feed the data into Opensearch. However, when creating the DataSource in the Opensearch Dashboard, I encounter an error, even though the connection test is successful.

Also please help me how we can create a metric Visualization for the metrics that are collected from Otel
