+
+An error code is a numeric or alphamueric code that indicates the nature of an error and, when possible, why it occured. 
+
+Dapr error codes are standardized strings for over 80+ common errors across HTTP and gRPC requests when using the Dapr APIs. These codes are both:
+- Returned in the JSON response body of the request.
+- When enabled, logged in debug-level logs in the runtime.
+  - If you're running in Kubernetes, error codes are logged in the sidecar.
+  - If you're running in self-hosted, you can enable and run debug logs.
+
+## Error format
+
+Dapr error codes consist of a prefix, a category, and shorthand of the error itself. For example:
+
+| Prefix | Category | Error shorthand |  
+| ------ | -------- | --------------- |
+| ERR_ | PUBSUB_ | NOT_FOUND |
+
+Some of the most common errors returned include:
+
+- ERR_ACTOR_TIMER_CREATE
+- ERR_PURGE_WORKFLOW
+- ERR_STATE_STORE_NOT_FOUND
+- ERR_HEALTH_NOT_READY
+
+> **Note:** [See a full list of error codes in Dapr.]({{< ref error-codes-reference.md >}})
+
+An error returned for a state store not found might look like the following:
+
+```json
+{
+  "error": "Bad Request",
+  "error_msg": "{\"errorCode\":\"ERR_STATE_STORE_NOT_FOUND\",\"message\":\"state store <name> is not found\",\"details\":[{\"@type\":\"type.googleapis.com/google.rpc.ErrorInfo\",\"domain\":\"dapr.io\",\"metadata\":{\"appID\":\"nodeapp\"},\"reason\":\"DAPR_STATE_NOT_FOUND\"}]}",
+  "status": 400
+}
+```
+
+The returned error includes:
+- The error code: `ERR_STATE_STORE_NOT_FOUND`
+- The error message describing the issue: `state store <name> is not found`
+- The app ID in which the error is occuring: `nodeapp`
+- The reason for the error: `DAPR_STATE_NOT_FOUND`
+
+## Dapr error code metrics
+
+Metrics help you see when exactly errors are occuring from within the runtime. Error code metrics are collected using the `error_code_total` endpoint. This endpoint is disabled by default. You can [enable it using the `recordErrorCodes` field in your configuration file]({{< ref "metrics-overview.md#configuring-metrics-for-error-codes" >}}). 
+
+## Demo
+
+Watch a demo presented during [Diagrid's Dapr v1.15 celebration](https://www.diagrid.io/videos/dapr-1-15-deep-dive) to see how to enable error code metrics and handle error codes returned in the runtime.

-## Error handling: Understanding errors model and reporting
-
 Initially, errors followed the [Standard gRPC error model](https://grpc.io/docs/guides/error/#standard-error-model). However, to provide more detailed and informative error messages, an enhanced error model has been defined which aligns with the gRPC [Richer error model](https://grpc.io/docs/guides/error/#richer-error-model).
