Is this project still supported? -- primo devenv suddenly not working for me

[Peredwel]

Hello,

I've been using primo devenv, and suddenly, this doesn't seem to be working for me. I'm running it from commandprompt with admin privileges with command gulp run --view 01OCUL_UO-UO_DEFAULT --ve and trying to access it at http://localhost:8003/discovery/?vid=01OCUL_UO:UO_DEFAULT, and I just keep getting the loading sign in the browser. I haven't changed the gulpfile or the config.js file in the gulp folder. Is it possible that any changes in the primo backend under Discovery>Display Configuration>Configure Views could affect this?

Thanks,
Carolyn.
