Failed to execute script gam

[Martin Vonášek]

Hi,

I reinstall my os (Ubuntu 19.04.), instal gam: bash <(curl -s -S -L https://git.io/install-gam), create a project (copy ID, secret) and got this: 

That's it! Your GAM Project is created and ready to use. 

I typed command gam info user and start authorization - select continue and allow all in my browser and got this:

[4989] Failed to execute script gam

I have tried it 3 or more times with same results - sometimes I couldn't open link for authorization (Error 400 in browser) and for first time I had to enable Google Cloud Platform for OU where is my admin account.

Thanks a lot for your respond

I don't know what to do - do you have any idea - please help?

Maybe I have the same problem like this: https://github.com/jay0lee/GAM/issues/479. Can I delete all file in bin/gam and try it again, or uninstall gam (how can I do it?).

Thanks for your help

Hi,

[Martin Vonášek]

I have found the solution (maybe) - I tried to create a new project (after deleting 2 json files from gam folder) and authentification link I selected and copied manually to web browser (Vivaldi) and it worked (but after restart computer after creating project - the first attempt finished with same error in Firefox).
