SyntaxError: Named export 'OperationGasParameters' not found.

I was trying this :
```import { Anchor, columbus5, AddressProviderFromJson, MARKET_DENOMS, OperationGasParameters } from '@anchor-protocol/anchor.js' ```
which has thrown me this error:
```
SyntaxError: Named export 'OperationGasParameters' not found. The requested module '@anchor-protocol/anchor.js' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from '@anchor-protocol/anchor.js';
const { Anchor, columbus5, AddressProviderFromJson, MARKET_DENOMS, OperationGasParameters } = pkg;
```
Any idea why it's happening?

The issue names no source files, tests, or entry points beyond the import from @anchor-protocol/anchor.js. Start by reproducing that import and inspecting the package's published module format and exports. Done means identifying why OperationGasParameters is unavailable as a named export and documenting the supported behavior or required package change.
