I have created a Groovy Script Report and am currently able to export it as HTML. I am now trying to export the report as a PDF but the CSS (which I specify using a file URL in my script) is not being applied.
If I were to specify the styles within the Groovy HTML Markup itself then the styles would be applied:
h1(style: 'color: #F00', 'Hello World')I am not sure if the CSS file URL is accessed upon the generation of the report, or if it is not accessed at all before the exporting to PDF. How should exporting of Groovy Script Reports to PDF be done properly?

Hi Johann,
if it works when you insert the styles in the HTML markup itself, you can use it like this.
For the file-based case, pls provide a minimal example and we will rise a ticket if this is a reportserver issue.

The issue with in-line styles for me is that it is not scalable and maintainable. Additionally, because my server requires a VPN to be accessed, users who do not have access to the VPN are not able to access these file URLs. (hence I am trying to generate the styles **before** actually sending the report, rather than have the CSS loaded client-side.
As a simple example, the following script generates a `h1` and `p` tag which should be styled with red and green respectively.
import groovy.xml.*
def writer = new StringWriter()
new MarkupBuilder(writer).html {
head {
link(href: <<CSS_LINK_HERE>>, rel: "stylesheet", type: "text/css")
}
body {
h1(style: 'color: red', "Hello World")
p("Give this p tag `color: green` in the CSS file.")
}
}
if(outputFormat == 'pdf')
return renderer.get("pdf").render(writer.toString())
return renderer.get("html").render(writer.toString())I am unable to provide a CSS link because as mentioned a particular VPN connection is required for access, but I have in my own file simply the following to style the `p` tag green:
p {
color: green
}Offline
Here is how I configured the Groovy Report on ReportServer:

In fact, after creating this simple example, when I try to export to PDF the addition of the CSS link causes the following error: https://ibb.co/HN89fkn

Hi Johann,
how exactly did you replace <<CSS_LINK_HERE>> ? can you pls post a concrete example of this?
I raised ticket RS-5900 for this issue, it is maybe a bug or an incorrect configuration.

Hi Eduardo,
One example I can give, similar to the file URL on the demo site (e.g. https://demo.raas.datenwerke.net/report … s?id=7398) is as such:
https://<<MY_IP_ADDRESS>>/reportserver/fileServerAccess?id=<<ID_OF_CSS_FILE>>I hope this helps. Let me know if more information is needed!

I also tried simulating the link with a link to the raw content of a GitHub gist, but I was not able to get it to work. (could be a firewall issue on my end, not too sure)
