[email protected] with emulator causes StringDecoder$DecodeBuffer error

[mpalmerlee]

[REQUIRED] Environment info

firebase-tools:
6.5.1

Platform:
macOS

[REQUIRED] Test case

Setup very similar to example here:
https://github.com/firebase/quickstart-nodejs/blob/master/firestore-emulator/typescript-quickstart/test/test.ts

[REQUIRED] Steps to reproduce

yarn global upgrade [email protected]
firebase setup:emulators:firestore
firebase serve --only firestore

Then run tests against local emulator

[REQUIRED] Expected behavior

Tests are passing with [email protected]

[REQUIRED] Actual behavior

lots of failures and in the local emulator console I see:

com.google.cloud.datastore.emulator.impl.util.WrappedStreamObserver onError
INFO: operation failed: com/google/api/tools/expr/parser/StringDecoder$DecodeBuffer

With the --debug flag I see basically the same thing with some more details at the top:

This error is in the security rules parser. Are you using custom rules? Would you mind attaching them so I can take a look?

[ryanpbrewster]

I can reproduce this and am working on a fix.

[mpalmerlee]

Oh great, let me know if you need anything else!

[ryanpbrewster]

More details:

• the v6.5.1 Firestore emulator will blow up on rulesets containing string or bytestring literals
• we'll roll out a bugfix for this ASAP
• until that release goes live you can downgrade to v6.5.0

[mpalmerlee]

That's awesome! Thanks for the quick response and fix for this @ryanpbrewster 🚀 🎉

[ryanpbrewster]

thanks for raising this issue
