'Error: Stream removed\n at /user_code/node_modules/grpc/src/client.js:554:15'

Environment details

• OS: Google Cloud Functions
• Node.js version: GCF version
• npm version: GCF version
• @google-cloud/datastore version: 1.3.3

Steps to reproduce

1. Perform a query in Datastore within a cloud function e.g.

const datastore = require('@google-cloud/datastore')({});

module.exports.myFunction = function() {
   datastore.get(key).then()....
}

This results in the above error. Same code works fine when run locally in Node (outside of cloud functions). I don't know whether this is more of a Cloud Functions bug or Cloud Datastore bug?

I got same error on my GCF project.
When my code was run at GCF, the code basically success but sometimes failed.
My case was below:

1. Deployed GCF project as HTTP triggers.
2. First access the endpoint, my code is failed(crushed).
   Errors are:
   • Unhandled rejection
   • Error: Stream removed at /user_code/node_modules/@google-cloud/datastore/node_modules/grpc/src/client.js:554:15
   • Function execution took 504 ms, finished with status: 'crash'

After crashed, I accessed to run datastore code then those code success...
But 30 min. ~ few hours later I accessed, sometimes code got the error...

@callmehiphop Do we just need to downgrade all of the places we have a grpc dependency to ~1.7?

[callmehiphop]

@stephenplusplus I believe that is correct :(

Anything we can do locally to workaround Google's bureaucracy with updates? This error is happening frequently here.

@dgadelha I ended up downgrading to datastore version 1.1.0 for the meantime and I am not seeing the errors in that version. It will be good if there is a more permanent official solution soon.

cc @bricktownseo who reported this in googleapis/nodejs-spanner#76

[stephenplusplus]

New and re-installations of @google-cloud/datastore should pick up the non-broken version of gRPC now. Please try it out and let me know if there are any issues.

[dgadelha]

Updated everything, didn't experience the issue so far.

[stephenplusplus]

Great, thanks for testing. Let me know if it reappears.

Could you open a new issue with details of the versions you're running, the environment you're in, and reproduction code?
