Using BigQuery plugin in Grafana

I have some issues with the format of the provisioning file. I have some service account file that looks like this 

{
  "type": "service_account",
  "project_id": "my-project",
  "private_key_id": "XXXXX_my_private_key_id_XXXXXXX",
  "private_key": "-----BEGIN PRIVATE KEY-----\nXXXXXXX_my_private_key___\nXXXXX_another_line_here_XXXXX\nXXXXXX_final_line_XXXXXX==\n-----END PRIVATE KEY-----\n",
  "client_email": "[email protected]",
  "client_id": "123456",
  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
  "token_uri": "https://accounts.google.com/o/oauth2/token",
  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/my-project%40company.iam.gserviceaccount.com"
}

And the provisioning file that I put in /etc/grafana/provisioning/datasources/all.yaml Which looks like this

apiVersion: 1

# list of datasources to insert/update depending
# what's available in the database
datasources:
  # <string, required> name of the datasource. Required
- name: bigquery-project
  type: doitintl-bigquery-datasource
  access: proxy
  isDefault: true
  jsonData:
  authenticationType: jwt
  clientEmail: [email protected]
  defaultProject: my-default-project
  tokenUri: https://accounts.google.com/o/oauth2/token
  secureJsonData:
  privateKey: "-----BEGIN PRIVATE KEY-----\nXXXXXXX_my_private_key___\nXXXXX_another_line_here_XXXXX\nXXXXXX_final_line_XXXXXX==\n-----END PRIVATE KEY-----\n"
  version: 2
  readOnly: false

But when I clicked on save and test I got some errors. I think I miss-formated the provisioning file. I tried to upload the service account file using the UI and the test passed, I was able to query BQ. However when I did this, I couldn't find any file in /etc/grafana/provisioning/datasources to get and example of it.

I'm executing a custom Grafana image in a docker container 

### file system hierarchy of the project
.
├── Dockerfile
└── provisioning
    ├── dashborads
    └── datasources
        └── all.yaml

### Docker file 
ARG GRAFANA_VERSION=6.5.3
FROM grafana/grafana:$GRAFANA_VERSION
ENV GF_AUTH_DISABLE_LOGIN_FORM "true"
ENV GF_AUTH_ANONYMOUS_ENABLED "true"
ENV GF_AUTH_ANONYMOUS_ORG_ROLE "Admin"
ENV GF_INSTALL_PLUGINS "doitintl-bigquery-datasource 1.0.4"

The way I'm running the container 

docker run -d -p 3000:3000 -v $(pwd)/provisioning:/etc/grafana/provisioning massy/custom-grafana

I'm providing the provisioning file via a volume.

What's wrong with the provisioning file ? When we add a datasource in Grafana, isn't the provisioning file updated automatically ? (if not created then it will be ?) How could I get the logs when I test that bigquery plugin ?

Edit

When I tried to add a dummy SQL query in "new dashbord" section this is what I get

 lvl=eror msg="Failed to get access token" logger=data-proxy-log error="private key should be a PEM or plain PKCS1 or PKCS8; parse error: asn1: structure error: tags don't match (16 vs {class:0 tag:28 length:110 isCompound:true}) {optional:false explicit:false application:false private:false defaultValue:<nil> tag:<nil> stringType:0 timeType:0 set:false omitEmpty:false} pkcs1PrivateKey @2"

I did a docker logs on the container

This is the correct format for the provisioning file

apiVersion: 1

datasources:
- name: bigquery-project
  type: doitintl-bigquery-datasource
  access: proxy
  isDefault: true
  jsonData:
     authenticationType: jwt
     clientEmail: [email protected]
     defaultProject: my-default-project
     tokenUri: https://accounts.google.com/o/oauth2/token
  secureJsonData:
     privateKey: |
        -----BEGIN PRIVATE KEY-----
        XXXXXXX_my_private_key___
        XXXXX_another_line_here_XXXXX
        XXXXXX_final_line_XXXXXX
        -----END PRIVATE KEY-----
  version: 2
  readOnly: false

There is a difference between the two provisioning files:

The one on GitHub has the correct format
