Attempting to utilize a default import to invoke an expression that does not have a call signature is not

I am currently experimenting with using https://github.com/arnaudbenard/redux-mock-store in conjunction with TypeScript. I have gone ahead and installed @types/redux-mock-store which includes the necessary export default createStore statement.

In my attempts to import the module, I have tried the following:

import createStore from 'redux-mock-store';

import * as createStore from 'redux-mock-store';

The first import does not raise any TypeScript errors, however, upon running the code, I encounter an issue where I receive the message redux_mock_store1.default is not a function.

On the other hand, the second import method works seamlessly during the test runs, but TypeScript throws an error stating "Cannot invoke an expression whose type lacks a call signature", suggesting that the default export of @types/redux-mock-store does not have compatible index signatures.

How can I effectively import or utilize this module to prevent any TypeScript error messages?

Answer №1

A recent update to redux-mock-store has caused a significant issue that is affecting both the library and its associated typings. More information can be found in the problem report on Github. To resolve this issue, it is recommended to roll back to the previous working version:
