Question

Is this the problem of js-docker-isolation-provider or @deep-foundation/tsx package? What should we do? The scariest thing is that I have been using handler code transpiled by that version of tsx package and everything was working. I do not know what is changed the way to brake it

I had conversation about this with chatgpt: https://chat.openai.com/share/452fcec7-ae51-49ab-9e0e-b22bd9c0e059

[FreePhoenix888]

If I run this file (test.ts):

async ({ deep, data: { newLink: notifyLink, triggeredByLinkId }, }) => {
};
export {};
//# sourceMappingURL=module.js.map

by using

npx ts-node --esm test.ts 

It will run without problem

If I run this file (test.ts):

eval(`
async ({ deep, data: { newLink: notifyLink, triggeredByLinkId }, }) => {
};
export {};
//# sourceMappingURL=module.js.map
`)

by using

npx ts-node --esm test.ts 

It will throw the error:

@FreePhoenix888 did you try to put export before the function? Our code expects that the last expression of the code string will be function expression.

[FreePhoenix888]

@FreePhoenix888 did you try to put export before the function? Our code expects that the last expression of the code string will be function expression.

The reason is - tsx now transpiles ts to esnext (or smth like that) but code is executed by eval by js provider

Eval does not know what export is

As workaround I remove this export

[konard]

@FreePhoenix888 I think we can close this issue in favor of #19

What do you think?
Or what is the specific reason to use export? Even if handler supports ts, why would you need to export anything from it?

I do not export smth manually, export is added itself when tsx bundles to jsx
