if a helm deploy operation on a sub-project fails or has an error an attempt to do a "helm deploy dev-vid .." cause a new onap release to be deployed name dev-vid such as dev-vid-aai, dev-vid-aaf etc.

Seems that

{{ # determine if upgrading individual subchart or entire parent + subcharts SUBCHART_RELEASE="$(cut d'' -f2 <<<"$RELEASE")"if [[ ! -d "$CACHE_SUBCHART_DIR/$SUBCHART_RELEASE" ]]; then
SUBCHART_RELEASE= else# update specified subchart without parent RELEASE="$(cut d'' -f1 <<<"$RELEASE")" fi}}

{{}}

can result in a blank SUBCHART_RELEASE and leads to bad deployment. Only recover is to delete the ONAP namespace and start over. We ahve run into this  multiple times {{}}
