Thank you very much. That config tweak did seem to help a lot.

Hi,
I've been migrating jsreport from my mac to an ubuntu server. My problem this time is that an html-to-xls template is bombing with:

My template uses Chrome html engine and has nothing in the xls asset (same on my local and ubuntu). On my local install Excel is already installed on the machine. Does it also need to be installed on the ubuntu machine for me to use that recipe? I'm not sure if this is a Chrome problem or Excel, but I'm able to produce other Chrome PDF reports.

Thanks

As in title, I have a couple reports that work on my mac that when cloned to Ubuntu do not work.
If important - I did have to delete some text in my settings file at Ubuntu after cloning for the reporter to initialize. Somehow it had text like "<<<<HEAD..." in it. So I deleted that stuff and then it did initialize.

I have one HTML report that runs fine so it seems like maybe html-to-xmls is my problem. Both non-working reports use that recipe.

The error one of the reports throws is:

2021-08-19T14:11:01.977Z - debug: Executing recipe html-to-xlsx

The other is :

I believe I followed the Ubuntu installation instructions exactly. This Ubuntu version is 18.04. I am cloning the /data folder only when I migrate.

Any advice?
Thank you

I didn't even know I had that option - that fixed it. Thank you!

Hi everyone.
This is so odd. I've just been running an HTML-to-xlsx report over and over (in studio) and it was working, when suddenly it started throwing this error:

2021-08-18T21:34:05.513Z - warn: Error when processing render request 1 Error while executing html-to-xlsx recipe. spawn Unknown system error -86 Error: Error while executing html-to-xlsx recipe. spawn Unknown system error -86

Switching over to HTML it's fine but I do need the to-xlsx version for a one formula.

I haven't thought of many things to try beyond killing the jsreport process and restarting, then opening studio in another tab.

Any ideas? Thank you

Thank you. This helped get it working again.

I'm cloning my local jsreport out to an ubuntu server and my logo references broke in the process.

I'm not a proficient linux user at all - if I have a logo sitting in /jsreportapp/data/logo.png and I want a report to display it by doing
<img background-color:transparent src = "logo.png" style="width:260px;"</img>

Can anyone help me with what the path in that tag would need to be? I feel like I've tried every thing I could think of:

logo.png by itself
/data/logo.png (really thought this would have been the answer)
/jsreportapp/data/logo.png
/home/ubuntu/jsreportapp/data/logo.png...which is pretty much all the way down.

When this was on my mac it was totally fine but this move has messed it all up.

I have tried to make this an asset but i couldn't get it to work that way.

Thank you

Good call. It was the node version. Had to update to 10-something to fix the error. Had to also add the new node /bin to environment variable.
Documenting in case this helps anyone with the same problem.
Thank you

Hi guys -
I have just installed jsreport on an Ubuntu server. I followed some instructions found here: https://jsreport.net/learn/ubuntu.
INstall seems totally fine until running a report.
My problem is that every one of my reports pulls from MongoDB so I have beforeRender script for them all and every one of them has to require('mongodb').MongoClient;

When I try to render a report I'm getting the error below. I can't find any information on "unable to require module mongodb".
I am really just migrating jsreport from my local mac to Ubuntu (I cloned reports into /data from a working install). I am not a proficient Ubuntu user so don't know why this might happen. Can anyone help?

confirmed: MongoDB ^4.0.1 is in package.json dependencies. Exact same report I am testing works in another environment (mac).

Error:

Hi, thanks for answering. My only reason for using it was that I thought I might have better luck with getting headers to work.

it does crash the jsreport process every time, even on the simplest possible template (no data, just a little text).

The only message that I see is that last line "Executing recipe phantom-pdf".

If you are saying phantom-pdf is basically deprecated I will abandon trying to use it. I'll post separately about my header difficulties if I can't figure them out.
Thanks
