steps to reproduce: 1. Launch marketplace app on your Firefox OS device 2. Click on Login/register 3. Enter an email address and set up password expected behavior: Log in is successful observed behavior: Logging in via persona fails with this JS error - [JavaScript Error: "Error: Syntax error, unrecognized expression: Persona authentication ." {file: "https://marketplace-dev-cdn.allizom.org/media/js/mkt/consumer-min.js?build=5be75cd" line: 12}]

Interesting. The view returns "Persona authentication failure" so it looks like the js in media/js/mkt/login.js is parsing that somehow?

login.js calls users.views.browserid_login, yeah. That's an assertion failure.

This happens every time? Is this a marketplace bug?

It happens every time there is a Persona assertion error. Instead, the error should be handled more gracefully. The reason it's happening every time for krupa is because she is on an unagi phone that has not been configured to use native b2g persona. The assertion will always fail without that.

Right now, we still haven't landed that pref on even though I've got checkin-needed. I'll go push back to get it landed.

Confirmed Kumar is correct - the current b2g shim requires the pref on.

I'm not sure what's going on anymore. Perhaps this change is related https://github.com/mozilla/zamboni/commit/b65fad4f#L2R346

Now I see this JS error: [JavaScript Error: "Error: Syntax error, unrecognized expression: Please use the verified email for this ." {file: "https://marketplace-dev-cdn.allizom.org/media/js/mkt/consumer-min.js?build=a918a1b" line: 12}]

FYI to those reading at home - we're officially prefed on now. Is comment 8 what we are getting when we are prefed on? Or does this bug even repo when we are prefed on?

We see this error even when pref'ed ON.

https://github.com/mozilla/zamboni/commit/499df4b https://github.com/mozilla/zamboni/commit/0660235 You'll now see the error. But, yeah this removes the JS error.

The JS error was fixed. Thanks, cvan!
