+**Status:** ![Development](https://img.shields.io/badge/-development-blue)
+
+The event name MUST be `faas.invocation.exception`.
+
+This event represents an exception that occurred during FaaS function invocation, such as application errors, internal failures, or other exceptions that prevent the function from completing successfully.
+
+This event SHOULD be recorded when an exception occurs during FaaS function invocation.
+Instrumentations SHOULD set the severity to ERROR (severity number 17) when recording this event.
+Instrumentations MAY provide a configuration option to populate exception events with the attributes captured on the corresponding FaaS span.
+
+**Attributes:**
+
+| Key | Stability | [Requirement Level](https://opentelemetry.io/docs/specs/semconv/general/attribute-requirement-level/) | Value Type | Description | Example Values |
+| --- | --- | --- | --- | --- | --- |
+| [`exception.message`](/docs/registry/attributes/exception.md) | ![Stable](https://img.shields.io/badge/-stable-lightgreen) | `Conditionally Required` [1] | string | The exception message. [2] | `Division by zero`; `Can't convert 'int' object to str implicitly` |
+| [`exception.type`](/docs/registry/attributes/exception.md) | ![Stable](https://img.shields.io/badge/-stable-lightgreen) | `Conditionally Required` [3] | string | The type of the exception (its fully-qualified class name, if applicable). The dynamic type of the exception should be preferred over the static type in languages that support it. | `java.net.ConnectException`; `OSError` |
+| [`exception.stacktrace`](/docs/registry/attributes/exception.md) | ![Stable](https://img.shields.io/badge/-stable-lightgreen) | `Recommended` | string | A stacktrace as a string in the natural representation for the language runtime. The representation is to be determined and documented by each language SIG. | `Exception in thread "main" java.lang.RuntimeException: Test exception\n at com.example.GenerateTrace.methodB(GenerateTrace.java:13)\n at com.example.GenerateTrace.methodA(GenerateTrace.java:9)\n at com.example.GenerateTrace.main(GenerateTrace.java:5)` |
