# JsonRpcError

> Base class for every error thrown by the SDK.

```typescript
class JsonRpcError extends DevinError
```

## Constructor

```typescript
JsonRpcError(message: string, code: number, data: unknown): JsonRpcError
```

### Parameters

**message** `string` *required*

**code** `number` *required*

**data** `unknown` *required*

### Returns

`JsonRpcError`

## Properties

**cause** `unknown`

**code** `number` *required*

**data** `unknown` *required*

**message** `string` *required*

**name** `string` *required*

**stack** `string`

**stackTraceLimit** `number` *required*

The `Error.stackTraceLimit` property specifies the number of stack frames
collected by a stack trace (whether generated by `new Error().stack` or
`Error.captureStackTrace(obj)`).

The default value is `10` but may be set to any valid JavaScript number. Changes
will affect any stack trace captured *after* the value has been changed.

If set to a non-number value, or set to a negative number, stack traces will
not capture any frames.

## Methods

### captureStackTrace()

```typescript
captureStackTrace(targetObject: object, constructorOpt?: Function): void
```

Creates a `.stack` property on `targetObject`, which when accessed returns
a string representing the location in the code at which
`Error.captureStackTrace()` was called.

```js
const myObject = {};
Error.captureStackTrace(myObject);
myObject.stack;  // Similar to `new Error().stack`
```

The first line of the trace will be prefixed with
`${myObject.name}: ${myObject.message}`.

The optional `constructorOpt` argument accepts a function. If given, all frames
above `constructorOpt`, including `constructorOpt`, will be omitted from the
generated stack trace.

The `constructorOpt` argument is useful for hiding implementation
details of error generation from the user. For instance:

```js
function a() {
  b();
}

function b() {
  c();
}

function c() {
  // Create an error without stack trace to avoid calculating the stack trace twice.
  const { stackTraceLimit } = Error;
  Error.stackTraceLimit = 0;
  const error = new Error();
  Error.stackTraceLimit = stackTraceLimit;

  // Capture the stack trace above function b
  Error.captureStackTrace(error, b); // Neither function c, nor b is included in the stack trace
  throw error;
}

a();
```

#### Parameters

**targetObject** `object` *required*

**constructorOpt** `Function`

### prepareStackTrace()

```typescript
prepareStackTrace(err: Error, stackTraces: CallSite[]): any
```

#### Parameters

**err** `Error` *required*

**stackTraces** `CallSite[]` *required*

#### Returns

`any`
