Prisma Client Having Syntax Issues with ??= Operator in RAGE:MP

[Radu28]

I’m having some trouble using the latest Prisma Client in my server. The generated Prisma code uses ES2021 syntax—specifically, the nullish assignment operator (??=)—which causes runtime errors.

 

Here’s what’s happening:

• When I build my project with Rollup and SWC targeting ES2019, I get errors like “Unexpected token ‘??=’” when the server runs.

• Also, there are module export issues coming from Prisma (like “Package subpath ‘./runtime/library.js’ is not defined by ‘exports’” in the Prisma Client package).

 

I’ve tried to configure SWC to transpile everything by including Prisma paths, but it still fails. I also tried marking Prisma as external so it wouldn’t get bundled, but then the runtime still hits the unsupported ES2021 syntax.

How to Reproduce:

1. Use the latest Prisma Client in a project.

2. Build with Rollup & SWC targeting ES2019.

3. Run the server in RAGE:MP.

4. See the error about the ??= operator and module export issues.

 

Question:

Has anyone here managed to bundle Prisma Client for RAGE:MP (or any ES2019 environment) successfully? How did you handle the modern syntax (like ??=) and export issues? Any tips, tricks, or workarounds would be awesome.

 

Thanks!
