![SFC Vision windows](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/c/0ca68f57a5fde0e16336892f442b896ce2b9436a.png) I got concern when I try to click the “Start The Chart” I always got in “error” SFC action, that tells client ID is missing. I follow and check the video demo on this topic, but I didn’t succeed. ---

What version of Ignition are you using, are there any errors in the logs (designer and gateway), what is the full stacktrace of any errors you are seeing, have you contacted support, etc? ---

This is 8.1.30, with regards on the error in the logs in gateway please find on the attachment. I still using the trial version to present on our client this week. Its Tank Track Loading Rack application which has a recipe and batch loading. Unfortunately the example on the SFC particularly the “Vision Client Interacting with SFCs” didn’t work as in the video tutorial. I follow all the instruction, but still, it goes to the error “Missing Client ID”. We hope you can assist us with regards on this concern, thank you. ![log error](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/8/88e4d165da1c9abf161c26b8ecbfa74e3128df23.png) ---

That error isn't coming from (first party) Ignition code - neither `FeedbackChart` nor `Missing Client ID` occur anywhere in our codebase. It's either a third party module or some custom logging someone set up somewhere in your project using `system.util.getLogger`. ---

Hi Paul, Thank you for your response on this concern. With regards on what you say, I’m just using a laptop, and I install the Ignition on a Hyper-V, so I don’t think there are any third party module or some costume logging. ---

What he is saying is that someone has made a script in the gateway you are using that generates that error log. That log does not originate from the Ignition code, its part of one of your projects that someone has built. ---

Hi David, Thank you for that clarification, so what do you think the best solution on this issue? ---

Search your project scripts for `system.util.getLogger("FeedbackChart")`. Or with single quotes, as jython allows either. Then examine that script for how it is used.
