Nope

[REQUIRED] Version info

node: 12.14.0

firebase-functions: 3.3.0

firebase-tools: 7.7.0

firebase-admin: 7.11.0

[REQUIRED] Test case

functions.https.onRequest(async (request, response) => {
        console.log(request.query) // Property query does not exist on type Request

        return response.send("ok")
})

[REQUIRED] Steps to reproduce

...

[REQUIRED] Expected behavior

I expect the type query to actually exist.

[REQUIRED] Actual behavior

functions.https.onRequest(async (request, response) => {
        console.log(request.query) // Property query does not exist on type Request

        return response.send("ok")
})

This has changed since I updated firebase-functions from 3.0.1 to 3.3.0. Downgrading doesn't seem to work. It is a typing issue with typescript.

Were you able to successfully deploy your functions?

Since I run TypeScript before deploying, no

I suspect this is the same root cause as #587. Something happened between 3.0.1 and 3.3.0 with one of the types dependencies I'm guessing.

Same here after upgrading from 3.3.0 to 3.6.0. In my case, it complains about such code:

functions.https.onRequest((_req, resp) => resp.end())

Property 'end' does not exist on type 'Response'

[ludovicfourrage]

Same for me after upgrading from 3.3.0 to 3.6.0

@ludovicfourrage what version of express are you on? If it is not version 4.17.3 or above, can you install that and see if that fixes the issue?

yarn upgrade fix my problem after upgrading firebase-functions from 3.3.0 to 3.6.0, and got these errors messages:

Found 6 errors.

error Command failed with exit code 2.

[joaoeudes7]

Any solution?

[tinaliang]

@joaoeudes7 could you try running npm i typescript@latest --save-dev to get the latest version of Typescript and let me know if that helps?

[asiFarran]

updating @types/express-serve-static-core helped resolve it for me.

npm install @types/express-serve-static-core

[JaapWeijland]

I'm having the same thing again. Installing @types/express-serve-static-core did not work for me.

[JaapWeijland]

I see the following: when I go to the "Type Definitions" of https.Request, it takes me to the file

functions/node_modules/firebase-functions/lib/providers/https.d.ts

There, on line 6, the following code is found:

export interface Request extends express.Request {
    rawBody: Buffer;
}

It is trying to extend from express.Request, but when hovering over express.Request, Visual Studio Code is not recognizing express.Request as a class (No type definitions found for Request). It is extending from nothing as far as VSC knows.

[JaapWeijland]

Alright, installing @types/express-serve-static-core actually did take away the initial express.Request error, but it brought in new definitions for request.query, which is why my code won't compile anymore. these new definitions are based on qs, according the the docs of Express an "extended parser". It is not the default behaviour of Firebase to use an extended parser, but the typing assumes it is using this parser.

Somehow the Firebase's variant of @types/express-serve-static-core is not shipped with the package.

[JaapWeijland]

Next findings: I had express installed next to firebase-functions. Deleting this from my package.json resulted in a correct install of firebase-functions, including @types/express-serve-static-core. The request.query typing problem persists though.
