qgis / qgis-js

Steps to reproduce:

Use the loadLocalProject function of @qgis-js/utils
When the system dialog to select a folder pops up, cancel it

Actual result:

Error "Uncaught (in promise) DOMException: The user aborted a request." appears
Rejected promise is not handled

Expected result:

Promise rejection is handled

Line 43 in f711af6

const loadLocalProject = () =>
Instead, loadLocalProject could be defined as an async function, like (not tested):

const loadLocalProject = async (): Promise<LocalProject> => {
  try {
    const entries: LocalEntries = await openLocalDirectory({
      recursive: true,
      mode: "read",
    }) as LocalEntries;
    const localProject = new LocalProject(fs, entries);
    return localProject;
  } catch (error) {
    console.error(error);
    throw error;
  }
};

This would allow to better handle e.g. user abortions in the UI.

Will have a look at this and fix it for the next release.

Probably we should add a a try-catch and reject the Promise of loadLocalProject in the catch clause. So it's up to the user of loadLocalProject if/how to handle this (e.g. do another call of loadLocalProject)

Thanks for the fix; this solves the issue.

qgis-js/utils - loadLocalProject does not handle promise rejections
