Hello, I'd like to report a problem I'm encountering when creating a tool. When selecting the HTTP request method, this error message appears (technical details of the error are below): Error: NotFoundError Message: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node. Timestamp: 2026-01-05T11:02:55:507Z Path: /tools/21742e79-dad4-4ec7-9edd-35ff31d9c409 I've already followed the advice I found through my research, such as: refreshing the page, creating a new tool from scratch, and ensuring that no request body is appended. I would appreciate any solutions. Looking forward to your reply, Best regards

Hi @Sanuka thanks for sharing the details, that error usually points to a UI state issue rather than your tool config. A few quick checks: does this happen in a specific browser only, and are you switching request methods after adding headers or params? I’ve also seen this when the tool editor desyncs after rapid changes, duplicating the tool before selecting the method can help isolate it. If you can confirm whether this occurs on a fresh tool with no headers, auth, or inputs defined, we can narrow it down fast. Happy to walk through it with you and help reproduce the issue if needed.

Could you please provide a screenshot or loom screen recording of the issue? We would like details about how to reproduce this
