"Unexpected end of JSON input" but only sometimes

[randall-coding]

When I first ran docker-compose up the install page would load up fine. It worked at first today also, but now it fails with a javascript error:
"Unexpected end of JSON input"

Full output:

Uncaught SyntaxError: Unexpected end of JSON input
at JSON.parse ()
at e.value (bundle.js:16:4483)

And the line in question on bundle.js is:

        }, {
            key: "getDepartments",
            value: function() {
                return JSON.parse(this.getItem("departments"))  #ERROR HERE
            }
        }, {

I'm currently trying this on Vivaldi browser.

Restarting with docker-compose up yields the same result.

Trying a new browser fixes the issue at first. Refreshing the page yields the same error again.

The solution right now is to start a new browser window in private mode.

Same problem here, except that it is systematic. However, switching to private mode browsing, as suggested (thanks btw, saved my day ...) solves the issue.
