Json data size limit?

[Daniele Franza]

Hello,

is there a limit in size data of Json files?
I have a large document of 5.8 MB and I give a 413 error "request entity too large".

Thank you
Daniele

hi! yes, there is a limit for the express routes that receive input but by default it is 50mb.

what is the action that throw this error? did you created a data entity and the error shows on save? can you show the full stack trace (probably visible on the console)?

I have a feeling this was nginx limit. Don't you use a webserver that just needs a proper config?

[Daniele Franza]

I think that it's a nginx limit. Please show attached screenshot.
The error message appears when I click on "Save" button.

Thank you for your help.

[jan_blaha]

Yes, so you need to properly configure nginx. The request doesn't even reach jsreport...

[Daniele Franza]

But it seems that the nginx problem is on jsreportonline.net domain, right?
So I think that I have nothing to do about that...
Thank you
Daniele

Ah I see, you use the jsreportonline.
Yes, unfortunately, there is this limit and you can't change it.
We will consider increasing it, but at this moment you can't save an entity bigger than 5mb.

These are your input data, right? You can still send them from the client or postman, but you won't be able to save them in studio.

Hello,

here you can see my code snippet.

The 5 MB nginx limit will occurs even in this case?
If so, how can I do to print this document?
Thank you

var paramsForRequest = {
    followRedirects: true,
    npmRequestOptions: {
        encoding: encoding ? encoding : null
    },
    headers:
    {
        'cache-control': 'no-cache',
        'authorization': reportEngine.authorization,
        'content-type': 'application/json'
    },
    data: {
        data: {},     // json data 5.8 MB
        template: {}  // jsreport template ref
    }
};

try {
    var res = HTTP.post(
        reportEngine.url, // https://techmakers.jsreportonline.net
        paramsForRequest
    );
    
    ...
}

The limit 5mb is just for saving entities.
Such render request as you have should work.

However the url should be https://techmakers.jsreportonline.net/api/report

I tried to do some modifications but still I can't print this large json file.

I use the asynchronous version of your library.

Now the 5.8 MB file is compressed (removing all spaces) in 3.4 MB but I have a 504 error.

Here some snippets of the HAR file:
