Macro Tasks left running after failed http requests with Unknown Error, preventing protractor from completing tests #38795
Description
🐞 bug report
Affected Package
@angular/common/http
Is this a regression?
Yes.
Worked in @angular/[email protected]
Description
A macroTask is left running when certain http errors occur and this prevents protractor for completing since there are tasks left running in the ngZone.
🔬 Minimal Reproduction
Run npm install
Run with npx ng serve
Open Chrome Browser to http://localhost:4200
Reproduce Bug
- Click Button Make Successful Request and see successul response.
- Click Button Check Task Counts and see the open micro and macro task counts in the ngZone.
- Click Button Make Failed Request and see the error response.
- Click Button Check Task Counts again and notice that the macroTask count is now 1.
- Repeat failed requests as many times as you like and the marcroTask count will just keep increasing.
🔥 Exception or Error
No macroTasks should be left running after this failed http request.
