That variable ('text') is the return value from (QGraphicsScene).addSimpleText(...), which is supposed to return a QGraphicsSimpleTextItem, not a QWebEngineUrlRequestInfo.

Though I get the same error in this ticket if I try to show the chain sequence via the link in the log ("'PySide6.QtCore.QUrl.toString' called with wrong argument types"), it works for me if I use the Show Sequences tool, unlike what happened in this ticket.

[Zach Pearson]

I think this is fixed for the same reason #18646 is fixed. I played around with Show Sequence Viewer and the log links and didn't encounter any tracebacks.

[Zach Pearson]

i.e. I think the second error is caused by the first error.
