Thanks Jan It is working for me 😁

Thank You so much Jan 🥺 for implementing this for me in such a short span of time . Will try and let you know it is working.😊😊

Sure Thanks waiting on you :)

Thanks Jan for your comments I think the issue was with this cat command which ignores the character '$' while creating files. So I used '\' as a escape character for saving it and it worked perfectly.
cat <<EOF >/var/jsreport/data/testTemplate/config.json

Hi Jan,
I am currently using jsreport-azure-storage npm package to save the Generated Reports in Azure Blob Storage and which uses the below configuration.

{
    "blobStorage": {  
        "name": "azure-storage", 
        "accountName": "...", 
        "accountKey": "...", 
        "container": "..."
     }
}

My Requirement is that I don't want to share the AccountKey and Account Name of Storage with anyone and hence we are using Managed Identities now for the Storage. and the generated Report must be saved using Managed Identities not using above configuration.

Please help me if you have something there to save the generated reports using Managed Identities.

Thanks,
Zahid Khan

Hi Jan,
I have created a shell script that will deploy my Jsreport on Ubuntu machine in Azure.

When I run the script everything went well and Jsreport Daemon service is also get created and it is running and all my Jsreport stuff is in jsreport folder and some templates are also configured by that script.

Issue is that I am not able to see those templates in jsreport studio.

My shell script create a testTemplate folder in jsreport/data folder where templates are stored and inside testTemplate folder script creates below files which are required for template.

1. config.json
   {
   "shortid": "Skg6lyHasL",
   "name": "testTemplate",
   "recipe": "text",
   "engine": "jsrender",
   "chrome": {
   "printBackground": true
   },
   "creationDate": "2020-05-28T13:39:17.492Z",
   "modificationDate": {
   "5840date": 1590673209303
   },
   "_id": "0Kog3miLXUG9Qwsx",
   "": "templates"
   }

2. helpers.js
   some java script content
   3.content.html
   some html content

I know that, in config.json the property for templates must be this "$entitySet": "templates" but when my shell script is trying to create that file somehow that key "$entitySet" is getting removed and it looks like "": "templates" in config.json file.

Below is my part of shell script that creates that config.json file
cd /var/jsreport/
sudo rm -rf data/
mkdir data
cd /var/jsreport/data/
mkdir testTemplate
cat <<EOF >/var/jsreport/data/testTemplate/config.json
{
"shortid": "Skg6lyHasL",
"name": "testTemplate",
"recipe": "text",
"engine": "jsrender",
"chrome": {
"printBackground": true
},
"creationDate": "2020-05-28T13:39:17.492Z",
"modificationDate": {
"$$date": 1590673209303
},
"_id": "0Kog3miLXUG9Qwsx",
"$entitySet": "templates"
}
EOF

Above peace of script will create a folder testTemplate inside data folder and config.json file is also get created.

Can you help me why this key $entitySet is getting empty by shell script and we are getting like this "": "templates".

Thanks,
Zahid Khan

Thank you Jan I am able to upload the blobs/reports to Azure Storage Service now.

Hi Jan,
I have Started a Ubuntu Server VM on Azure Cloud and installed the JsReport on it and then created a Storage Account as well to store the Reports in Azure Storage Account.

When I am trying to Generate a report from my .Net core application the generated report should be stored in Storage Blob in Specifed Container as mentioned in Jsreport config.

While generating report the report get's generated successfully and Container is created in Azure Storage Blob Service but the Report/Blob is not stored in Azure Storage. You can see the Jsreport Logs below and the error I am getting.
