How can I determine the actual cause of this fault? I'm concerned that when deployed the fault will happen and crash the website.

Hello @timmackey, can you observe your RAM usage while this error occurs?
0

timmackey created 3 years ago

Do you mean system RAM? I have 16 Gigs installed on my dev machine. Client Node.js is 1.5G at startup.
Dev Studio Diagnostic Tools reports 489M Process Memory at startup. I'll take a snapshot of these memorys next occurrence of the fault. Or should I be looking at something else?

Hi Tim,

Can you change gulp buildDev && ng serve --host 0.0.0.0 --port 4200 in package.json to ng serve --host 0.0.0.0 --port 4200 and see if it makes any difference. We are planning to remove gulp buildDev as well since it causes delays in development time.

I think this is just related to development time.

timmackey created 3 years ago

before change:

  "scripts": {
    "ng": "ng",
    "publish": "gulp build && ng build --prod",
    "start": "gulp buildDev && ng serve --host 0.0.0.0 --port 4200",
    "hmr": "gulp buildDev && ng serve --host 0.0.0.0 --port 4200 --hmr",
    "test": "gulp buildDev && ng test",
    "pree2e": "webdriver-manager update --standalone false --gecko false",
    "e2e": "gulp buildDev && protractor",
    "create-dynamic-bundles": "gulp buildDev"
  },

after change:

  "scripts": {
    "ng": "ng",
    "publish": "gulp build && ng build --prod",
    "start": "ng serve --host 0.0.0.0 --port 4200",
    "hmr": "gulp buildDev && ng serve --host 0.0.0.0 --port 4200 --hmr",
    "test": "gulp buildDev && ng test",
    "pree2e": "webdriver-manager update --standalone false --gecko false",
    "e2e": "gulp buildDev && protractor",
    "create-dynamic-bundles": "gulp buildDev"
  },

Thank you for the suggestion.

Hi @timmackey

Did that fix the problem for you ?

So far so good. I need a couple of weeks of dev to make sure it doesn't happen again.

Hi @timmackey

Can you reproduce it on a new project ?

This error consistently happens in the following scenario:

In Visual Studio Code start debug session with Chrome browser.
login as user [email protected]
use website
logout
open Chrome browser.
navigate to localhost:4200.
login as user [email protected]
node server crashes as soon as home page is displayed.

Hi,

Could you upgrade node to latest version and try again ?

Hi @timmackey

Sorry for the missing information. I was suggesting node 14.x (Not LTS but current).

Could you upgrade to Node 14.x and try agian ?

Did you try this on any other machine ? If so, did you face the same problem.

Thanks,

Have not tried on another machine. The easiest way to try on another machine would be to clone the SDD and plug disc into another laptop of identical HW. I doubt the outcome would be different, given the OS and all drivers, apps, packages are identical. The hard way would be to install all dev tools, apps and packages from a HDD set to original factory settings, which might have a different outcome. This would take a lot of time, and if the error goes away, the root cause would still remain unknown. Open to other diagnostic suggestions.

Hi @timmackey

Could you try to download a new Demo project and run the same steps ? If problem doesn't happen, could you share your angular project with us via email (to [email protected]) ?

UPDATE Asp Net Zero version 8.1.0 Core 3.1/angular Angular CLI: 8.3.29 Node: 14.12.0 OS: win32 x64 Angular: 8.2.14

The error reported in this issue is intermittently occurring only under the following conditions:

Login as host admin

In the Tenant management page, login as a non-admin tenant.

Perform some actions as tenant/user

Return to admin user via "Back to my account".

The reported error occurs.

Hi Tim,

Thanks. Do you run the Angular app from VS Code ? If so, could you try running it from command line and see if it causes the same problem.

You can also try to add a direct dependency as explained here to webpack/webpack-dev-server and see if it fixes the problem.
