"Cannot GET /"

Everything builds ok but when the browser launches I just get an error "Cannot GET /" when it tries to load http://localhost:21196/ Any ideas why?

Hi,

open node.js command. change into the directory  ClientApp.

run ng serve --open

then you can see the problem.

 

 

UPDATE: Added attachment showing conflict in account.service.ts, at first glance everything seems legit, but still looking

Hey, I'm having the same issue and plan to jump into it shortly, but wanted to share the output you requested.

Node.js command prompt:

C:\Users\eric\source\repos\BlankCordovaApp1\QuickApp\Quick Application1\Quick_Application1\ClientApp>ng serve --open

Hello again. This worked for me although I don't know what impact it will have. If there's a better solution, I'd be interested.

I removed the second OperatorFunction parameter sent to .pipe

See here

updateRole(role: Role) {
if (role.id) {
return this.accountEndpoint.getUpdateRoleEndpoint(role, role.id).pipe(
tap(data => this.onRolesChanged([role], AccountService.roleModifiedOperation)));
}
else {
return this.accountEndpoint.getRoleByRoleNameEndpoint<Role>(role.name).pipe<Role>(
mergeMap(foundRole => {
role.id = foundRole.id;
return this.accountEndpoint.getUpdateRoleEndpoint(role, role.id)
}));
//,
//tap(data => this.onRolesChanged([role], AccountService.roleModifiedOperation)));
}
}

I have the same problem!

........
return this.accountEndpoint.getRoleByRoleNameEndpoint<Role>(role.name).pipe<Role>(
........

The signature of the pipe "pipe<Role>" is incorrect. It should be: pipe<never, never>  or you can simply choose to make it implicit pipe.

So the line:

return this.accountEndpoint.getRoleByRoleNameEndpoint<Role>(role.name).pipe<Role>(

becomes:

return this.accountEndpoint.getRoleByRoleNameEndpoint<Role>(role.name).pipe(

Updates in the typescript compiler checks for these rules. This has been updated in upcoming versions of QuickApp.
