# Class: FitParsingError

Defined in: [packages/core/src/domain/types/fit-errors.ts:25](https://github.com/pablo-albaladejo/kaiord/blob/3eacbe62ef72342d970523967cc5155b5935bb85/packages/core/src/domain/types/fit-errors.ts#L25)

Error thrown when FIT file parsing fails.

This error is thrown by FIT readers when they encounter corrupted files,
invalid FIT data, or unsupported FIT features.

## Example

```typescript
import { FitParsingError, convertFitToKrd } from '@kaiord/core';

try {
  const krd = await convertFitToKrd(fitReader, validator, logger)({
    fitBuffer: corruptedBuffer
  });
} catch (error) {
  if (error instanceof FitParsingError) {
    console.error('FIT parsing failed:', error.message);
    console.error('Cause:', error.cause);
  }
}
```

### stackTraceLimit

> `static` **stackTraceLimit**: `number`

Defined in: node_modules/.pnpm/@types+node@26.6.5/node_modules/@types/node/globals.d.ts:67

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.

#### Inherited from

`FormatParsingError.stackTraceLimit`

## Methods

### captureStackTrace()

> `static` **captureStackTrace**(`targetObject`, `constructorOpt?`): `void`

Defined in: node_modules/.pnpm/@types+node@26.6.5/node_modules/@types/node/globals.d.ts:51

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`

##### constructorOpt?

`Function`

#### Returns

`void`

#### Inherited from

`FormatParsingError.captureStackTrace`

### prepareStackTrace()

> `static` **prepareStackTrace**(`err`, `stackTraces`): `any`

Defined in: node_modules/.pnpm/@types+node@26.6.5/node_modules/@types/node/globals.d.ts:55

#### Parameters

##### err

`Error`

##### stackTraces
