Can you say why this error came ? and how to fixs it ?

I have a senario where i need to create a Template for email in JSreport and show it in my angular app. the user can modify the report content and when they click sent button The edited content should be the body of the email. IS this possible with JSReport ?
I use .Net as server side.

when i try to render a report following error occurs. Can you help me understand the reason for this issue.

I have set my report time out as 1200000. Still, sometimes the following error arises.
Can you explain this and give me a solution if possible?

I tried paralization by dividing the data into multiple chunks and sending those as multiple requests to the report.

when I do that this issue arrives.! Can you help me to find the issue and solution

I have a scenario where we print reports of 3000pages or more, Since we know it takes time to render it, Is there a way to calculate the time it takes to render the report and show it to the client or show some percentage of the progress bar for the rendering done?

I have a report which shows single or multiple person photos in it, the problem is that I pass the image URL in <img> tag some time the server the image is stored on is down and the report takes time waiting to access the server, is there any timeout for solving this issue in configurations?

Sure.In the Data[ ] list "INC[ ]" array has a list of 40000 indexes.

just multiply the contents in the "data:[ ]"
