Firebase Functions Cannot find name 'BigUint64Array', ''BigInt', ''BigInt64Array' - google-cloud-functions

Question

Dependencies:
"dependencies": {
"cors": "^2.8.5",
"firebase-admin": "^8.6.0",
"firebase-functions": "^3.11.0",
"nodemailer": "^6.4.11"
},
"devDependencies": {
"firebase-functions-test": "^0.1.6",
"tslint": "^5.12.0",
"typescript": "^3.2.2"
},
Description:
Since updating to firebase-functions 3.11.0, I get following error when trying to deploy my functions with firebase deploy --only functions:
node_modules/#types/jsdom/ts3.5/index.d.ts:8:24 - error TS2304: Cannot find name 'BigInt'.
8 BigInt: typeof BigInt;
~~~~~~
node_modules/#types/jsdom/ts3.5/index.d.ts:9:31 - error TS2304: Cannot find name 'BigInt64Array'.
9 BigInt64Array: typeof BigInt64Array;
~~~~~~~~~~~~~
node_modules/#types/jsdom/ts3.5/index.d.ts:10:32 - error TS2304: Cannot find name
'BigUint64Array'.
10 BigUint64Array: typeof BigUint64Array;
~~~~~~~~~~~~~~
Found 3 errors.
Even going back to the previous version doesn´t seem to solve the issue, so I´m not sure if the update was the trigger.

I think I have it. From npm #types/jsdom I went to package homepage where I found this part.
It seems that you need to install additional package:
npm install --save-dev #types/node
I have replicated this issue with firebase init and replacing package.json with yours. I got the same issue than. After package install with above command my function was deployed with no errors.
One remark: you do not have #types/jsdom in package.json, which according to my understanding should be there. I have installed this package before replacing the file, to have similar situation.
