The `finally` function in promises is failing to execute properly

Question

The `finally` function in promises is failing to execute properly

Currently working with Typescript and I've included

import 'promise.prototype.finally'

at the beginning of my index.js file (in fact, I've added it in multiple places).

Whenever I try to use a promise, I encounter the error message saying

client.get(...).then(...).finally is not a function

.

I'm confused about why this isn't functioning as expected. Additionally, I'm unsure what additional details I can provide for troubleshooting or where to seek assistance regarding this issue!

Your guidance would be greatly appreciated.

Answer №1

To implement the functionality of the package promise.prototype.finally, it is important to note that simply importing the package does not automatically activate its features. You must import it with a specified name, as shown below:

import promiseFinally from 'promise.prototype.finally';

After importing, utilize the shim() function to apply the patch to the global Promise prototype:

promiseFinally.shim();

Once this process is complete, you can use the feature as intended in your code.

For optimal organization, consider placing these lines at the beginning of your main entry point file. If such a file does not exist, ensure to add them at the top of any files where their usage is expected.
