Post-registration action works in testing but not when deployed

I’m using LinkedIn Social / OAuth login to register and sign-in users with Auth0. On their first log-in (registration) I want an action to create a “user” object/document in FaunaDB using the Auth0 “event.user” JSON object that was created from the data passed by LinkedIn. I wrote the script for it in the action’s part of post-registration-flow, tested it with the FaunaDB secret key (it worked great), deployed it, set up the action flow, and it’s just not passing the new user’s info to FaunaDB after a user’s first login using LinkedIn Social Sign In.

Is there an error log for actions that I can view? Is LinkedIn social login technically not considered a registration even though user member is created in Auth0’s “User Management” tab? Am I messing up the Auth0 Actions configuration? I’d greatly appreciate any insight. Thanks so much, everyone!

exports.onExecutePostUserRegistration = async (event) => {

      ) {
  const sendQuery = async (query, variables) => {
  const {
    data: { data, errors },
  } = await axios({
    url: '',
    method: 'POST',
    headers: {
      Authorization: `Bearer ${event.secrets.FAUNA_SECRET_KEY}`,
    data: {
  if (errors) {
      throw new Error('Something went wrong on sendQuery');
  return data;

  const formattedResponse = (statusCode, body) => {
      return {
          body: JSON.stringify(body),

  try {
      const { createUser } = await sendQuery(

      return formattedResponse(200, createUser);
  } catch (err) {
      return formattedResponse(500, { err: 'There was an error in creating a new user.' });


Should have searched the community first. Social/enterprise logins don’t count trigger actions as per this thread:

I do wish this counted as registration since a new member is created in the “User Management” tab in Auth0. Is there a technical or user requirement reason why it’s not?

Please mark this thread as resolved. Thanks everyone.
