How to handle the results of Promise.all() in a typescript project

When working with TypeScript, I encountered an issue while trying to assign the results of Promise.all(). It seems that Promise.all() changes the return type to number | <actual type>. Even when attempting to handle this inside a then() statement... Is there a solution for this?

Answer №1

It seems that the change in type is not caused by Promise.all() itself, but rather by the catch block which returns the output of array.push().

By modifying the error handling to:

.catch(err => {
    errors.push(err);
    return {};
});

this issue appears to be resolved.
