Error in `restore_or_initdb.sh` while restoring a backup

What happened?

I tried to restore a backup with the timescale-single helm chart. I faced this error:

2023-08-07 08:56:13 - restore_or_initdb - Attempting restore from backup

I followed the admin documentation: So, I created the secret pgbackrest-bootstrap.

apiVersion: v1
stringData:
    PGBACKREST_REPO1_S3_BUCKET: xxx
    PGBACKREST_REPO1_S3_ENDPOINT: s3-eu-west-1.amazonaws.com
    PGBACKREST_REPO1_S3_KEY: xxx
    PGBACKREST_REPO1_S3_KEY_SECRET: xxx
    PGBACKREST_REPO1_S3_REGION: eu-west-1
    PGBACKREST_REPO1_CIPHER_TYPE: aes-256-cbc
    PGBACKREST_REPO1_CIPHER_PASS: xxx
    PGBACKREST_TARGET_ACTION: promote
    PGBACKREST_TYPE: time
    PGBACKREST_DELTA: "y"
kind: Secret
metadata:
    name: pgbackrest-bootstrap
type: Opaque

Then I edited my values.yaml files:

#1: Enable bootstrapFromBackup
bootstrapFromBackup:
  secretName: pgbackrest-bootstrap
  enabled: true
  # /!\ To change
  repo1-path: /k8s-namespace/helm-release-name

#2: Disable backup
backup:
    enabled: false

#3: Manually add PGBACKREST_TARGET env var
# We do notinclude this in the `pgbackrest-bootstrap` secret otherwise we have a parsing error because of the space character.
env:
- name: PGBACKREST_TARGET
  value: 2022-08-02 08:00:00.0000+00

The issue is that pgbackrest info and pgbackrest restore share argument --type but with different values.

This line of restore_or_initdb.sh causes the issue.

Did you expect to see something different?

The restore process should work.

How to reproduce it (as minimally and precisely as possible):
