I try to work on an Angular application whose setup precedes me (certain trouble). After angular-cli installation on local machine by commands below, I run "sudo ng serve -o". The first error log appears below. The suggested solutions were the update of angular cli and build angular or comment the line "es5BrowserSupport": true on angular.json . Only the latter changed the prior log.
>> sudo npm install -g @angular/cli
// Installation log ommitted
>> ng serve -o
Schema validation failed with the following errors:
Data path "" should NOT have additional properties(es5BrowserSupport).
>> sudo ng update @angular/cli
>> sudo ng update @angular-devkit/build-angular
>> ng serve -o
An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.
See "/tmp/ng-Q6e3Kl/angular-errors.log" for further details.
After research through foruns, the common solution was to downgrade the build-angular by typing the following command.
>> npm i @angular-devkit/build-angular@0.803.24
// Installation log ommitted
>> ng serve --o
An unhandled exception occurred: Job name "..getProjectMetadata" does not exist.
See "/tmp/ng-R1gyui/angular-errors.log" for further details.
I can't proceed further. Any help is appreciated and if needed, I can provide additional information.
Best regards, Bruno Peixoto
