We have deployed jsreport (4.10.1) on a dedicated VM in the Production environment.
Configuration is as follows -
RAM: 32GB
CPU: 4 Cores
Architecture: x64
(non-containerised)
numberOfWorkers: 1

We keep getting Worker terminated due to reaching memory limit: JS heap out of memory once in a while. And it gets crashed and restarts after that.

Could you please let us know if we need to change any configurations or settings to avoid this issue?

Following is the error screenshot:

Let us know if you need any additional details.

We have some queries:

Could you please let us know the default heap size?

How many percentage of RAM should be allocated to heap?

If we have set only one worker then why are we getting heap size limit issue?

Do references held by previous renders get freed up after report rendering finishes?

Please let us know so that we will be able to monitor and set appropriate configurations.

We want to use jsreport-cli without installing it globally.

While running it for import from \node_modules\.bin folder, where jsreport was hosted as an application, but we faced the following error:

Although the "@jsreport/jsreport-cli": "^4.0.5" package is installed in the hosted application.

Couldn't find a jsreport installation necessary to continue with the execution of the command, make sure to install jsreport first.

Could you please guide us on how to perform the jsreport import-export activity without installing it globally?

Why don’t the other properties, like pdf margin top, get applied to this PDF?

I am unable to print a web page to PDF.

I want to convert https://tomastrajan.github.io/angular-ngrx-material-starter#/examples/stock-market to PDF. But it should wait for the page to complete visually. and then start the PDF generation. But seems it is not working.

Tried the following approach, but it times out.

Getting the following issue on reverting uncommitted changes. We are using MongoDB storage.
Any suggestions to troubleshoot this?

MongoServerError: Updating the path '@odata' would create a conflict at '@odata' at UpdateManyOperation.execute (/app/node_modules/mongodb/lib/operations/update.js:101:19) at process.processTicksAndRejections (node:internal/process/task_queues:105:5) at async tryOperation (/app/node_modules/mongodb/lib/operations/execute_operation.js:203:20) at async executeOperation (/app/node_modules/mongodb/lib/operations/execute_operation.js:73:16) at async Collection.updateMany (/app/node_modules/mongodb/lib/collection.js:231:16) at async Object.update (/app/node_modules/@jsreport/jsreport-mongodb-store/lib/provider.js:236:19) at async persistChanges (/app/node_modules/@jsreport/jsreport-version-control/lib/main/versionControl.js:172:29)...

Thanks very much!

We are currently using async reports and sending multiple asynchronous requests to jsreport. As expected, jsreport adds these requests to its queue.

We’ve configured the reportTimeout setting to 45 minutes. However, we’ve observed that the timeout countdown begins as soon as the request reaches jsreport — not when the actual report execution starts.

Ideally, we were expecting the reportTimeout to start only once the report begins execution, rather than from the time it enters the queue. Could you please confirm if this is the intended behavior? If so, is there a recommended approach to handle longer queue times without prematurely triggering the timeout?

These async reports, as well as others in the queue, failed due to the 45-minute timeout being reached. The delay was caused by earlier async reports that were still pending in the queue.

Yes MS Excel in Windows.

I understand that browser preview is a black box.

But the following screenshot is from the Excel that I created manually on my PC. In that the complete text is visible.

But the file that is generated using jsreport does not show the complete text.

If we create an Excel manually on our PC with the same content, in that case, the behaviour is the same, like if the rest of the cells are empty, the complete text is visible.

It is when the file is generated using jsreport with same text width and cell content, the text is not visible. What could be the cause?
