When I try to run wolframscript for the first time, here is what happens
$ wolframscript The Wolfram Engine requires one-time activation on this computer. Visit https://wolfram.com/engine/free-license to get your free license. Wolfram ID: email@example.com Password: The Wolfram Engine exited during an activation attempt because of a license error: invalid activation key entered.
I already went to
https://wolfram.com/engine/free-license and activated my license
I tried with two different accounts on two different computers, and it failed with both.
