Steps to reproduce

1. vagrant up runbox

Notes

I have tried to uninstall vagrant, delete ~/.vagrand.d folder, and install vagrant again. The error still persists

Hi there @andythsu - It looks like the debug log you provided does not contain the error mentioned. Do you have the debug log showing the JSON error? Also do you have a Vagrantfile? Thanks.

Hi Brian, the debug log does not show the JSON error unfortunately, and I am not able to provide a vagrant file as it contains sensitive information. Do you really need to see the Vagrantfile?

[andythsu]

@briancain Also, I have updated the gist, it should show the JSON error now

[briancain]

@andythsu Have you tried removing the local .vagrant directory inside your project directory?

[andythsu]

@briancain ya.. I deleted it and re-ran the command. It's proceeding without the error anymore. Hopefully it doesn't happen again. Thank you

[briancain]

@andythsu - thanks! Sounds good. Sometimes that file gets corrupted but it isn't really clear how it happens. The best fix is usually just removing it and Vagrant is typically good to go! If it happens again and you figure out how it happens feel free to open another issue.
