ScriptApp.getService().getUrl() points to dev URL. How can I get it to point to exec production URL?

Question

ScriptApp.getService().getUrl() is generating a dev URL. How can I make it generate the exec production URL?

Answer 1

For those poor souls that get here, an expansion on J. G.'s comment: confirmed that the result of the getService().getURL() call is dependent on which URL (/exec or /dev) is accessed by the end-user.

There is also an explicit clarification on that (not sure if it was present before) in the method documentation, so it seems to be by-design:

If you are running the development mode web app, this returns the development mode URL.

Note that to get the correct URL you need to use a workaround suggested by Tanaike. When using it, remember that it requires a standard GCP to enable the Apps Script API (technically, you can use a default one for that, but it will only work for G Suite (Google Workspace) accounts with access to system-gsuite/apps-script/ resources).

An implementation of deployment getter would be:

const getDeployments = (options = {}) => {
  const {
    version = 1,
    id = ScriptApp.getScriptId(),
    token = ScriptApp.getOAuthToken(),
    page = "",
    size = 50,
    type = "WEB_APP",
  } = options;

  const uri = `https://script.googleapis.com/v${version}/projects/${id}/deployments`;

  const fullURI = `${uri}?pageSize=${size}${page ? `&pageToken=${page}` : ""}`;

  const params = {
    contentType: "application/json",
    headers: {
      Authorization: `Bearer ${token}`,
    },
    muteHttpExceptions: true,
    method: "get",
  };

  const deps = [];

  const response = UrlFetchApp.fetch(fullURI, params);

  if (response.getResponseCode() !== 200) {
    console.log(response.getContentText());
    return deps;
  }

  const { deployments, nextPageToken } = JSON.parse(response.getContentText());

  const requested = deployments.filter(({ entryPoints }) =>
    entryPoints.some(({ entryPointType }) => entryPointType === type)
  );

  deps.push(...requested);

  if (nextPageToken) {
    deps.push(...getDeployments(options));
  }

  return deps;
};

After a successful response, check the entryPoints collection to get the deployment you need. Each entry point will have a webApp nested object - you are interested in the url property of it.
