### Bug description While experimenting with Treemap charts in the Explore view, clicking the “Samples” tab triggers a request to "/datasource/samples". The backend responds with HTTP 200 but an empty body. The frontend loader spins for some time, and then the UI freezes. STEPS TO REPRODUCE IT: 1- Run Superset in Docker (latest dev build - Docker Compose). 2- Go to the charts tab and create a Treemap chart using any dataset. 3- Click the “Samples” tab (bottom right). 4- Observe loader spins, UI freezes, and no data shown. Expected Behavior: The Samples tab should display rows or show a “No data available” message or something like that. Actual Behavior: The UI freezes after receiving a 200 response with no content. ### Screenshots/recordings <img width="1914" height="956" alt="Image" src="https://github.com/user-attachments/assets/d7720c6e-feb2-46ec-b5fe-01020f41034d"; /> HERE IS THE SCREEN RECORDING OF THAT EXACT ISSUE : https://github.com/user-attachments/assets/2423b73e-52de-410e-9102-5bf4d67b04e6 ### Superset version master / latest-dev ### Python version 3.11 ### Node version 18 or greater ### Browser Chrome ### Additional context Any Dataset will give the same response. I have checked it multiple times. Backend log snippet : POST /datasource/samples?force=false&datasource_type=table&datasource_id=1 HTTP/1.1" 200 - ### Checklist - [x] I have searched Superset docs and Slack and didn't find a solution to my problem. - [x] I have searched the GitHub issue tracker and didn't find a similar bug report. - [x] I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section. -- This is an automated message from the Apache Git Service.
