Google-cloud-ruby: LoadError when retrieving document from Firestore

[jurvis]

I'm currently trying to use google-cloud-firestore to access the contents of my Cloud Firestore. However, whenever I run .get on my DocumentReference, I get this error:

LoadError: cannot load such file -- grpc/grpc_c
from /Users/jurvistan/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/bootsnap-1.7.3/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:23:in `require'

Sample Code:

> firestore = Google::Cloud::Firestore.new
> a = firestore.doc("foo/<hard-coded document uid>")
=> #<Google::Cloud::Firestore::DocumentReference:0x00007fe212bd4768
 @client=#<Google::Cloud::Firestore::Client:0x00007fe212c3ec58 @service=Google::Cloud::Firestore::Service(...)>,
 @path="projects/.../databases/(default)/documents/foo/..."> 
> a.get

Any idea what might be the problem here?

Hi @jurvis, can you please provide the library versions in your environment, most importantly the grpc version?

[quartzmo]

Also, your operating system and any other relevant details about your environment. Thanks!

The error you are seeing is most likely caused by: https://github.com/grpc/grpc/issues/25222

Here's a workaround for Ruby 3.0, grpc 1.36.0, and OS X:

% bundle update
Fetching gem metadata from https://rubygems.org/..........
Resolving dependencies...
...

Fetching grpc 1.36.0 (universal-darwin)
Installing grpc 1.36.0 (universal-darwin)

...

Bundle updated!

% gem install grpc --platform=ruby
Fetching grpc-1.36.0.gem
Building native extensions. This could take a while...
Successfully installed grpc-1.36.0
Parsing documentation for grpc-1.36.0
Installing ri documentation for grpc-1.36.0

% gem uninstall grpc              

Select gem to uninstall:
 1. grpc-1.36.0
 2. grpc-1.36.0-universal-darwin
 3. All versions

hi @quartzmo, thank you for responding so quickly!

I followed those steps you posted exactly but now get a different error:

[2] pry(main)> firestore.doc("foo/...").get
LoadError: cannot load such file -- /Users/jurvistan/.rbenv/versions/3.0.0/lib/ruby/gems/3.0.0/gems/grpc-1.36.0-universal-darwin/src/ruby/lib/grpc.rb

Here's what I get when I run gem info --local grpc:

I still see grpc-1.36.0-universal-darwin in your new backtrace. There's some staleness there but I'm not sure why.

[quartzmo]

The output from gem info --local grpc looks ok to me, but for some reason your runtime (pry, bootsnap) is looking for grpc-1.36.0-universal-darwin.

[quartzmo]

Anyway, the workaround above is probably not a great solution for anyone. If you use Bundler, it keeps re-installing grpc-1.36.0-universal-darwin.

[quartzmo]

Here's the grpc PR that promises to fix the error:

https://github.com/grpc/grpc/pull/25429

[jurvis]

I managed to get the workaround to work!

It's a bit silly, but after you mentioned staleness in my pry runtime, I remembered I had forgotten to reload my Rails console. thank you!

[quartzmo]

This was fixed in grpc v1.37.0! 🎉
