Prisma generate on windows using deno fails with "Unsupported 16-bit Application" error.

[konuch]

When I try to generate and use prisma on Windows following the official manual at https://deno.com/manual@v1.34.3/node/how_to_with_npm/prisma I end up with following error on windows.

I used following command: deno run -A npm:prisma generate --data-proxy

Environment:

Deno:
deno 1.34.3 (release, x86_64-pc-windows-msvc)
v8 11.5.150.2
typescript 5.0.4

Windows:
Edition Windows 10 Enterprise
Version 22H2
Installed on ‎4. ‎11. ‎2021
OS build 19045.3086

Can you try to use Prisma via Node.js and see if you get the same error?
If so, please to report this in https://github.com/prisma/prisma/issues

Funny enough I just got a similar error message:

I have no idea what exactly happened, besides that I updated the Prisma version that Deno was using with this, it downloaded the engine files, and then ran into this error.

Probably related to this, this output:

@konuch We assume this has been fixed in #21297. Could you try your steps again with Deno v1.38.3?

[janpio]

For me it is indeed fixed now, or at least I could not trigger it any more. Nice.

[bartlomieju]

Gonna close this one since it appears fixed.
