In my project after a certain version, no matter what I asked to do, the output remains a blank white screen. In v25 I have working code. In v26 and on, no matter how many troubleshooting attempts, it is blank. If I return to the working version and modify the request, same thing. Blank. I have forked the working version and asked for a change. Again: Blank. I have taken the working version and a broken version, plugged them into chatGPT o1 to compare and identify the issues. I provided v0 with the output to address issues noted to fix the blank output.
So the current behavior is everything renders. When I ask it to update pattern recognition to put certain characters into tokens nothing renders. Below is one iteration that is broke. Below that is the link to see it all.
v26 does not work:
