Triggered auto assignment to Contributor-plus team member for initial proposal review - @hungvu193 (External)

[hungvu193]

@lschurr I want to discuss about the expected behavior here. In this case, when we sent an invalid phone number, the whisper message shouldn't be displayed or it's displayed but we can't click the Invite button?

[lschurr]

I'm not 100% sure - Would you mind starting a Slack thread to discuss @hungvu193?

[hungvu193]

I raised on slack:
https://expensify.slack.com/archives/C01GTK53T8Q/p1714617971723469

[hungvu193]

Coming from Slack, I think we should handle this issue from BE (BE won't send the whisper action if that's invalid mention), @lschurr can you please add the Internal label?

[melvin-bot]

Current assignee @hungvu193 is eligible for the Internal assigner, not assigning anyone new.

[lschurr]

Asked in the Slack thread about best ways to move forward here. I think we need an Eng volunteer to assign this to.

[blimpich]

I'll pick this up, I think it'll be a quick fix.

Notes for myself:

Looks like we have a couple ways in Web for validating a phone number, though we should probably only have 1. We also have ways of validating it from the client; one way to validate it is via a command called IsValidPhoneNumber (which doesn't appear to be used ever in App) but we also have ways that leverage other libraries as shown here. Auth doesn't seem to have methods for validating phone numbers, which seems odd to me.

Another funny thing is that we also seem to be making accounts for these invalid phone numbers. Like when you comment @+91 it actually creates an account with the username +91@expensify.sms, even though we would reject making that account if a user tried to sign up with it. Not sure if we care about that or not. We probably don't care.

It seems like this will be easiest to fix in Web. But that may be problematic because I think these actionable mention whispers are made in Auth. We may need to port over our TwilioUtils.php file to Auth, or at least partly port it. That would take a little bit of time. But I think that would be the "best" solution since a Web solution will probably end up being quite hacky. Those are my thoughts after doing an initial inspection.

Will return to this tomorrow.

[blimpich]

Ugh, this is more complicated than expected. Twilio uses the E164 format as their standard for what is and isn't a valid phone number, but this standard actually doesn't have a minimum number of digits necessary for it to be valid. See https://www.twilio.com/docs/api/errors/21211. This means that I don't think we can actually say that these phone numbers are invalid.

So, technically, +91 is a valid phone number. And if you can believe it, according to the leading SMS api in the world, even + is a valid phone number. Kinda ridiculous.

I tested this by directing hitting Twilio's api using our own TwilioUtils->isValidPhoneNumber method in Web-Expensify
.

But we don't allow numbers like that to make accounts! If you type +94 into the login page it'll tell you that's not a valid number!

The reason is because we use the awesome-phonenumber npm package to partly validate our phone numbers. And for some reason it seems to understand that +94 is not a valid phone number, probably due to a very long if/else chain checking country code against phone number length. For example, Sweden only has to have 7 digits in their phone numbers (source).

Funnily enough this package is actually based off a C++ package from Google called libphonenumber. So we could download that into our C++ layer and start using that, but this is getting a little ridiculous.
