cloud manager issues with frontend build

Hi Team -

has anyone seen issues with frontend app build with cloud manager. our application has a jest file for module mapper of aliases. In cloud manager those aliases are not resolved but resolved in mac in local. the module mapper looks like below -

Could not locate module @utilities-root/Constants mapped as:
/build_root/build/test/frontend/meijer-ui/src/main/content/jcr_root/apps/test/utilities$1.

{
"moduleNameMapper": {
 "/^@utilities-root(.*)$/": "/build_root/build/test/frontend/meijer-ui/src/main/content/jcr_root/apps/test/utilities$1"
"resolver": undefined

so it can identify the correct modulemapper from the list. but never resolves the $1.

Any input is appreciated.
