Azure B2C gives "undefined" as the error message when signing up with a duplicate account

Ryan White 36

Using the default template, on a SignInSignUp flow with no customization the web service returns:
{"status":"400","errorCode":"ViralErrorUserCreationConflict","message":"A user with the specified ID already exists. Please choose a different one."}

But the UI gives undefined as the error:

It appears to be a bug on Microsoft's part, any way to fix this? Is there somewhere to file this bug report?

Hi @Anonymous , is the comment in this thread from you? Trying to see if it's not just you experiencing this. Have you tried using a different browser and seeing if anything changes? Please let me know and I can help you further.

Thank you,
James

The reply is me but I am not the original poster of the issue. Myself and 3 members of our team have been able to replicate the issue in Chrome and Edge. Also I can replicate in multiple tenants with a default or custom template. Replicating is simple, sign up with an email address to a local account on a B2C tenant, then sign up again with the same email address.

Here's an Edge screen shot.

Hi,

I am experiencing the same thing when trying to verify an email for a user that doesn't exist. I would expect an error message such as "email address does not exist" or "invalid email", but instead it just says "undefined"

Thanks,
Kezia

Hi, we are having the same issues. in our test environment.

the issue is coming from the User Flow- Page Layout version. the 2.1.19 is generating this issue. I move to an older version 2.1.9 (Which is a version that we have our dev user flow version) and now we don't have the error anymore

Also, I can't see the associated entry in the localized resources.
is it the source of the issue? (no default error message for the page layout version?)

what is the correct StringId for localized resource?

Hi @Anonymous @Kezia Shirazi @Baud, Patrick , I'm going to escalate this since it seems something is broken on our end. I'll reach out as soon as I have an update.

Best, James

We are still seeing undefined in the front end, did the hotfix get deployed? I see a new Page Layout version 2.1.19 but setting to that version did not help.

Hi @James Hamil Is this issues resolved? We started facing this very recently on our production. Strangely, our test instance is not facing this issues. Let me know the latest update.

Is there any movement on this issue? This comment was from January, but we're still experiencing this issue.

Can we get an update?

We are experiencing the same behavior - interestingly it happens only on our prod tenant and works fine on our dev environments (using exactly the same versions)

Hi,

Any update on this fix? We are getting this error for duplicate EmailID signup in both production and dev. Ideally it should have shown "Account already exists" message. We tried last 3 versions but we get the same error.

From what we discovered, a version that is supposed to fix that issue is just not available in the portal for some reason. cf https://github.com/MicrosoftDocs/azure-docs/issues/112663
