Steps to reproduce

Start Node:

Code node：

HTTP node:

When the prompt and urls in the HTTP node receive values from the Start node, the request works normally. However, when the prompt and urls in the HTTP node receive values from the Code node, a 400 Bad Request error occurs. What is the reason for this, and how can it be resolved? This issue exists in both versions 1.8.1 and 1.9.0.

What's even more puzzling is that it worked fine yesterday, but today it doesn't work at all, even though no changes were made.

✔️ Expected Behavior

The HTTP node can normally receive values from the Code node.

❌ Actual Behavior

No response
