Intermittent CORS Error when Localhost Extra Logging Enabled

[jbranson000]

Expected Behaviour

No CORS error(s) would occur when using the app using aio app run

Actual Behaviour

Intermittent CORS error(s) occur when using aio app run, particularly if our app generates multiple requests in a short amount of time.

The issue can be locally remediated by disabling the extra logging code (below) in firefly\hexagon\src\dx-excshell-1\web-src\src\utils.js: /*if (window.location.hostname === 'localhost') { actionHeaders['x-ow-extra-logging'] = 'on' }*/

However, disabling this logging can prove problematic for a couple of reasons:

1. Disabling it will sometimes cause the latest runtime actions to revert to an version that is ~4-5 versions older than the current version.
2. Depending on how our logging is configured in actions - we lose visibility into our action console/log calls themselves.

Reproduce Scenario (including but not limited to)

See steps below. I'm also happy to demo it with our app, if necessary.

Steps to Reproduce

1. Disable the extra logging headers in utils.js as described above.
2. Load any app builder app, and try to exceed the logging limit threshold by firing off several action requests in quick succession. Again, the issue is intermittent - but once it does start occurring it typically continues until you restart the app.
