Storyshots Integrity › Abandoned Storyshots › encountered a declaration exception

[ValeryIvanov]

Issue details

So this is rather strange situation. When running Stroyshots in my dev machine everything passes. When I run them in CI server in docker env, I get following error

> node scripts/test.js --env=jsdom "--coverage"

 => Loading custom .babelrc
 FAIL  src/Storyshots.test.js

    "@storybook/addon-storyshots": "^3.3.8",
    "@storybook/addons": "^3.3.8",

I assume that you need to grant this permission, am I missing something? In fact, we have these tests running here in CI, and everything is fine

[ValeryIvanov]

Hmm how would I grant this permission? Could you elaborate a bit more please?
Is it something I need to do in Dockerfile?

[igor-dv]

Actually, I'm not sure now.
Here is this open issue in glob package.

Maybe you can try to create some test app that executes const storyshots = glob.sync('**/*.storyshot'); and run it in your CI? BTW I assume that /proc/1/map_files/55cf41c57000-55cf41c73000 doesnt contain storyshots ?

Just changed working directory in Dockerfile and no more error.
