An Error Event is one immutable error occurrence, with breadcrumbs and correlation.

**Service** Sylphx Observability · **Resource type** `observability.sylphx.com/ErrorEvent` · **Name pattern** `orgs/{org}/projects/{project}/envs/{env}/error_groups/{error_group}/error_events/{error_event}` · **Shape** `record`

## Fields

| Field | Type | What it is |
| --- | --- | --- |
| `name` | `string` | `orgs/{org}/projects/{project}/envs/{env}/error_groups/{error_group}/error_events/{error_event}`. |
| `uid` | `string` | `err_<cell><ulid>`; never reused. Output only. |
| `meta` | `ResourceMeta` | Resource metadata. |
| `event_time` | `timestamp` | When it happened. Required. |
| `exception_type` | `string` | The exception type. Required. |
| `message` | `string` | The exception message. |
| `stack_frames` | `StackFrame[]` | Stack frames, innermost last. |
| `service_name` | `string` | The emitting service. |
| `release` | `string` | The release the emitter ran. |
| `breadcrumbs` | `Breadcrumb[]` | Breadcrumbs before the error, oldest first, at most 100. |
| `tags` | `map<string, string>` | Typed tags, at most 64. |
| `fingerprint` | `string` | Override the grouping fingerprint. |
| `trace_id` | `string` | W3C trace id (32 hex). |
| `span_id` | `string` | W3C span id (16 hex). |
| `stack` | `string` | The stack as the runtime printed it (JavaScript `Error.stack`), at most 64 KiB. When `stack_frames` is empty, V8 (`at fn (file:line:col)`) and Gecko/WebKit (`fn@file:line:col`) lines are parsed into `stack_frames`, innermost last; when `stack_frames` is set, it wins and `stack` is kept as sent. Either way the frames are then mapped through the source maps uploaded for `release` before grouping. Scrubbed before storage. |
