Provided you have built the frontend with "--prod" flag,
when you try to create a new pool by clicking on "Add"
you see a blank page instead of the pool creation form.

EXPLANATION

In "master > do_cmake.sh" we have:

${CMAKE} -DCMAKE_BUILD_TYPE=Debug $ARGS "$@" .. || exit 1

This flag

CMAKE_BUILD_TYPE=Debug
that is causing that although yo do:

cd /ceph/build

make mgr-dashboard-frontend-build

... you are building in dev mode (not PROD mode) because of this:

src/pybind/mgr/dashboard/CMakeLists.txt:

if(NOT CMAKE_BUILD_TYPE STREQUAL Debug)
set(npm_command npm run build -- --prod --progress=false)
else()
set(npm_command npm run build -- --progress=false)
endif()

Once you do the frontend build with --prod in master, you are able to reproduce it.

=> A PROVISIONAL HOTFIX In src/pybind/mgr/dashboard/frontend/src/app/app.module.ts

Add:

import { ErasureCodeProfileService } from './shared/api/erasure-code-profile.service';

[...]

providers: [
[...] {
provide: ToastOptions,
useClass: CustomOption
},
ErasureCodeProfileService // <==== Here is the provisional hotfix.
],

IMHO the whole workflow should be reviewed under PROD environment to ensure
that everything is OK.
