Error Logging In Using Phone Number As Identity

User Service
1

I got the following error when using UserService.login after changing my users table identify column to use the phone number as the identity column rather than the email column. The issue is solved for me, but I thought someone might be interested in the error. The cause was that I had renamed the “phoneNumber” column in the user table to “phone”. Apparently, it is hard-coded somewhere.

Backendless encountered an error while handling the request. An internal trouble ticket with ID 5DD80A71-4FC3-D0AB-FF2C-4EDC455D7F00 has been created and we will be investigating the issue.

Hello @Kelly_Oglesby,

Thanks for reporting this issue.
Unfortunately we couldn’t reproduce it.
Could you please provide your APP ID and the step by step description to reproduce this problem?

Hi Olha,

My app id is 43953016-3AB4-478E-A6C9-91937A61F288. I simply changed the identity column of my Users table in the console from the email column to the phone number column. When I used the UserServices.login method in the Javascript SDK from my client, passing a phone number and password, I got the reported error. I had renamed the phoneNumber column to “phone” a long time ago. As soon as I changed it back to “phoneNumber”, the error went away, and the call now works perfectly, like everything else in Backendless. :>) So I am a very happy customer - no further effort is required or expected on my end! I only reported in case someone was actively working an automatic trouble ticket, as was mentioned in the error message.
