Cannot access to the web app locally

[StephaneConq]

Expected Behaviour

Actual Behaviour

Server starts correctly, I can go to http://localhost:8080, but this error occurs when trying to log to this page :

Steps to Reproduce

I did all the steps until part 2 step 6.
By the way, the app works normally on AppEngine.

AppEngine config

Google Cloud SDK 280.0.0
app-engine-python 1.9.88
app-engine-python-extras 1.9.87
bq 2.0.53
cloud-datastore-emulator 2.1.0
core 2020.02.07
gsutil 4.47

Bazel config

Build label: 2.1.0
Build target: bazel-out/k8-opt/bin/src/main/java/com/google/devtools/build/lib/bazel/BazelServer_deploy.jar
Build time: Fri Feb 7 13:01:04 2020 (1581080464)
Build timestamp: 1581080464

My config

Distributor ID: Ubuntu

You're using way too new of a version of Bazel. Please use 0.26.1.

https://github.com/google/loaner/blob/master/docs/gngsetup_part2.md#step-1-set-up-a-development-computer covers this. Give that a try and let me know if you're still having issues.

Did not read that correctly indeed
Yet I now have another error :

What commit are you using from GitHub git log should provide this commit info? I would personally recommend master right now since 0.7.1a has some issues I've seen with compiling. We should hopefully be cutting a numbered release soon.

[StephaneConq]

Thanks again for your answer, I've been using this commit :

commit ab5e35d
Author: Mike Helfrich me@michaelhelfrich.com
Date: Mon Oct 7 11:18:16 2019 -0400

Internal change.

PiperOrigin-RevId: 273295181

[helfrichmichael]

@StephaneConq yeah, that commit probably won't work without some additional modifications (due to changes in packages we are reliant on). I'd recommend swapping to the master branch. We fixed much of the OSS build in 5f898ff. The master branch will include that commit.

You can see our branches here.

Hi,

Sorry for the late answer, I was on another project.
So I followed your call and based myself on the latest commit on master :

Author: Mike Helfrich me@michaelhelfrich.com
Date: Wed Apr 1 13:33:24 2020 -0400

CHANGE: Set Travis CI to update apt before installing packages. This should resolve Chrome being viewed as unauthenticated.

PiperOrigin-RevId: 304214060

But I still have the first error when logging in (the RuntimeError: no suitable implementation for this system: IOError(13, 'file not accessible') error)

Everything is up to date, Bazel is at the correct version.
Thanks in advance for yourr help.

[helfrichmichael]

Is that error only occurring when you try to run the local server or also when you do a dev push?

[StephaneConq]

No that error only occurs when trying to login in local server with dev_appserver.py

[helfrichmichael]

I found this article, but haven't had a chance to investigate/try this.

It looks like it might be caused by a newer version of Google Cloud SDK. If you feel comfortable trying to troubleshoot this using that article, feel free to let us know if it resolves the issue. Otherwise, it will be a bit before I can look into this probably.
