Solution

It seems "Argon Dashboard Pro Angular" was not completely migrated to Angular11. Some packages are still using an old incompatible version (ie: @angular/http:7.2.16 ).
You can also try to run "ng update @angular/cli", "ng update @angular/core" and "rxjs" to see some current issues with the migration to Angular 11.

I tried to manually update the old packages but then ran into this issue:
"FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory"

Hi @perseghini,

Thank you for working with our products.

We tried updating but we also receive this fatal error. We will still try to fix it and we will come with updates.

Thank you,

Hi @fb2062,

Please replace in package.json "@angular/common": "^11.0.5" with "@angular/common": "11.0.5", delete node_modules and package.lock.json and install the project.

Please let me know if it works.

Thank you,

Can this solution be added to the README? Maybe as a 'Gotcha' suggestion in the event, a user encounters this error? My company bought this theme today and this would have saved us some time if it was included in the README.

Thank you for building this theme.
