Hello everyone,

First of all, thank you to Auth0 for this wonderful product as well as the community on here.

For the problem I’m facing:

I’m trying to host a React app on Heroku with Auth0 and everything is working OK locally. But when I try to login on Heroku it ends up giving me a 404 on the callback route.

Earlier I hadn’t provisioned an Auth0 addon on Heroku but then I did that and tried with my new clientId and new authdomain which was a new url(Idk if I should use it) but still getting a 404 on the callback.

Has anyone ran into the same problem?

I searched for solutions on the forum but none worked for me.

Thanks

Hey there @yash592 and welcome to the Auth0 Community! When you get a chance can you please capture the login workflow that is producing the error within a HAR file. Please keep in mind to select “Preserve log” to catch redirects and scrub the file of user passwords before passing it over in a direct message. I also have included a extensive bog article we did that talks about deploying JS apps which on particular part relates to Heroku for reference. Thanks in advance!

I wanted to follow up @yash592 and see how things are coming on obtaining that HAR file. Please let me know if you have any questions. Thanks!
