Helm chart: reference a secret gives name: %!s(<nil>)-%!s(<nil>) - kubernetes

Question

I am creating a Helm chart. When doing a dry run I get a error:
Error: YAML parse error on vstsagent/templates/vsts-buildrelease-agent.yaml: error converting YAML to JSON: yaml: line 28: found character that cannot start any token
The dry run also outputs the secret and deployment YAML file which I created. The part where it goes wrong in the deployment shows:
- name: ACCOUNT
valueFrom:
secretKeyRef:
name: %!s(<nil>)-%!s(<nil>)
key: ACCOUNT
- name: TOKEN
valueFrom:
secretKeyRef:
name: %!s(<nil>)-%!s(<nil>)
key: TOKEN
The output from the dry run for the secret looks fine.
The templates I created:
apiVersion: v1
kind: Secret
metadata:
name: {{ template "chart.fullname" . }}
type: Opaque
data:
ACCOUNT: {{ .Values.chart.secret.account }}
TOKEN: {{ .Values.chart.secret.token }}
apiVersion: apps/v1
kind: Deployment
metadata:
name: {{ template "chart.fullname" . }}
labels:
app: {{ template "chart.name" . }}
chart: {{ .Chart.Name }}-{{ .Chart.Version }}
release: {{ .Release.Name }}
heritage: {{ .Release.Service }}
spec:
updateStrategy:
type: RollingUpdate
template:
metadata:
labels:
release: {{ .Release.Name }}
app: {{ template "chart.name" . }}
annotations:
agentVersion: {{ .Values.chart.image.tag }}
spec:
containers:
- name: {{ template "chart.name" . }}
image: {{ .Values.chart.image.name }}
imagePullPolicy: {{ .Values.chart.image.pullPolicy }}
env:
- name: ACCOUNT
valueFrom:
secretKeyRef:
name: {{ template "chart.fullname" }}
key: ACCOUNT
- name: TOKEN
valueFrom:
secretKeyRef:
name: {{ template "chart.fullname" }}
key: TOKEN
The _helper.tpl looks like this:
{{/* vim: set filetype=mustache: */}}
{{/*
Expand the name of the chart.
*/}}
{{- define "chart.name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{/*
Create a default fully qualified app name.
We truncate at 63 chars because some Kubernetes name fields are limited to this (by the DNS naming spec).
*/}}
{{- define "chart.fullname" -}}
{{- $name := default .Chart.Name .Values.nameOverride -}}
{{- printf "%s-%s" .Release.Name $name | trunc 63 | trimSuffix "-" -}}
{{- end -}}
Where am I going wrong in this?

I missed 2 dots....
- name: ACCOUNT
valueFrom:
secretKeyRef:
name: {{ template "chart.fullname" . }}
key: ACCOUNT
- name: TOKEN
valueFrom:
secretKeyRef:
name: {{ template "chart.fullname" . }}
key: TOKEN
