Hi, I couldn't include extra log file, as I was running this inside a GitHub action.

Likely a duplicate of #130769

[theemathas]

The error output shows that the panic occurs while compiling the http-body dependency, so the mcve would be the same as the one there.

[jieyouxu]

Ah right, then is indeed a duplicate of #130769.
