Does this also happen to the "Hello world" reports? Or only for longer ones?

Have you checked the Ubuntu installation steps for Chrome dependency?

Please try to share a minimal playground demo that I can review.
https://playground.jsreport.net/

The problem can be a CSS issue, for example.

Any chance you would be able to email me (share a private link to some kind of onedrive) what you have in the env where you import and the import file you are uploading? I would profile the operation to find out the bottleneck. (jan.blaha@jsreport.net)

At this moment, you should be able to prepare separate blob storage and when you are confident, switch the production env to it.

The problem with blob storage is that it is significantly slower to work with than a DB or file system. We need to perform many small operations, which are slow in total. This driver was implemented 10 years ago, because there were no other simple options. Nowadays, you can share a managed disk or Azure Files, which provides better performance in this case. This is just to clarify the poor performance on big imports with azure storage.

How do you persist your templates? Is it to a azure file share? A disk? A blob storage?
Does this happen only for full import with many entities ? Does it happen also if you import something small?

I've pushed the fixed jsreport/jsreport:4.10.0-full
Please clean your images cache and try it again.

Note that the unoconv extension is deprecated. You should use libreoffice extension instead.

I appologize, the playground should be fixed now.

And can you help or guide, which is the method for use in production?
Is better use api or browser-client?
Which is the correct plan we have to paid?

I'm not sure what you mean here. Typically the best choice is to host on prem jsreport in your cloud provider.
And typically better to use the backend API and route requests to jsreport through your API to keep jsreport as the backend isolated service.

Hi,

I appologize for the inconvenience. The integration with email service was temporarily broken.
Please try again.

You have the following options...
Try to add also the --disable-site-isolation-trials arg.
Try to use a different CDN like jsdeliver, cdnjs
Use a proxy
Download the minified lib and upload it as an jsreport asset.
Install it from npm, using npm extension for example, and use it with module helper

Yes, this is an old config that broke it. Please keep it removed and use only reportTimeout root config.
