Why the requested route is being trimmed while rendering?

[abhinayts]

I have a React application using next js, after Next 12 upgrade I am observing that requested route is being trimmed while rendering.
Any idea what is that I am missing? Any configuration needs to be changed?
It is deleting 44 character at the starting of the URL.
Also observing below error, not sure if it is related.
TypeError: Missing parameter name at 15

Any help highly appreciated.
