firebase deploy error TS1005

[nchitnis1]

I am following the instructions from https://firebase.google.com/docs/ml/ios/recognize-text.

I tried this on the Mac, and also on Windows 10, with exactly the same results.

git clone https://github.com/firebase/functions-samples
cd vision-annotate-images
cd functions
npm install
cd ..
firebase init
firebase deploy --only functions:annotateImage

The output has 136 errors, I am showing just the top few:

@nchitnis1 Thanks for the feedback. It turns out the issue is with old typescript version included in the sample.

To workaround the issue, try installing the latest version of typescript:

npm i --save-dev typescript@latest

I also sent PR to the samples repo to fix the issue upstream.

I reinstalled everything and added the changes made above, and it works now. Thanks.
