Unable to remove X-Frame-Options header via ignition.conf (Parameters ignored in wrapper.log)

Ignition

Hi everyone,

I am trying to embed an Ignition WebDev Python Resource (HTML) into Power BI Desktop using the HTML Content visual. Currently, the content is being blocked because the response header X-Frame-Options is set to SAMEORIGIN.

I have attempted to remove this header and set the CSP by modifying ignition.conf, but the Gateway seems to completely ignore these parameters.

What I have configured in ignition.conf: I added the following lines to the wrapper.java.additional section. I ensured the numbering is continuous (my previous line is .9) and there are no commenting # characters at the start.

wrapper.java.additional.9=-Dedition=
wrapper.java.additional.10=-Dignition.http.header.X-Frame-Options=
wrapper.java.additional.11=-Dignition.http.header.Content-Security-Policy="frame-ancestors *"

Troubleshooting Steps Taken:

  1. Restarted Gateway: I performed a hard restart via Windows services.msc (Restart Service). I also tried using stop.bat and start.bat with Admin privileges.

  2. Verified Syntax: Checked for hidden spaces, confirmed no # signs, and verified the numbering sequence is unbroken.

  3. Checked Browser: After restart, Chrome DevTools (Network tab) still shows X-Frame-Options: SAMEORIGIN.

  4. Checked wrapper.log (CRITICAL ISSUE): I inspected the wrapper.log after the restart. I can see other parameters being loaded, but the lines for X-Frame-Options and Content-Security-Policy are completely missing from the log. It seems the wrapper is not reading these specific lines at all.

My Question: Why would the Ignition Gateway (or Java Wrapper) ignore valid wrapper.java.additional parameters in the config file? Is there a Windows permission issue (like VirtualStore) or a caching mechanism that prevents ignition.conf changes from being picked up even after a service restart?

Any help would be appreciated. I've been stuck on this for days!

Thanks.

In the manual these system properties use underscores and lowercase: Gateway and Gateway Network Parameters | Ignition User Manual

I’m not sure there’s even a setting for CSP.

Where did you get these properties you’re trying to use from? Based on your post I’m guessing the answer is an LLM…
