I am facing issues with the dependency pinning after adding Firebase to my golang project with Nakama.
May you guys know which configuration I should use?
Thanks,
Daniele
Hello @ilmalte, what version of Nakama are you running and what does your plugin go.mod file look like?
Thanks for the quick reply @sesposito.
For context, I wanted to add FCM for push notifications so I added:
go get firebase.google.com/go/v4/messaging
go get firebase.google.com/go/v4
go get google.golang.org/api/option
This is the error I get when I run the docker compose up.

I am currently using 3.20.0 but I also tried to change the version to 3.21.1 and I still get the error.

This is my very first golang project and I am struggling a bit to fix this issue 
The following should work using Nakama 3.21.1 and considering the dependencies you have in your files above:
go.mod:
go 1.21
require (
firebase.google.com/go/v4 v4.13.0
github.com/heroiclabs/nakama-common v1.31.0
github.com/minio/minio-go/v7 v7.0.67
golang.org/x/oauth2 v0.15.0
google.golang.org/genproto/googleapis/api v0.0.0-20231212172506-995d672761c0
google.golang.org/genproto/googleapis/rpc v0.0.0-20231211222908-989df2bf70f3
google.golang.org/grpc v1.60.0
google.golang.org/protobuf v1.31.0
)
You should also add the following to your plugin main.go imports:
import (
_ "firebase.google.com/go/v4"
_ "github.com/minio/minio-go/v7"
_ "golang.org/x/oauth2"
_ "google.golang.org/genproto/googleapis/api"
_ "google.golang.org/genproto/googleapis/rpc/status"
_ "google.golang.org/grpc"
)
Do not forget to run go mod tidy && go mod vendor after you apply these changes.
This one was a bit hairy, we should be releasing Nakama 3.22.0 soon, at which point we should bump all of its dependencies which may require some changes here if you upgrade.
Given this example and following our dependency pinning guide, hopefully you can work through it if needed.
Hope this helps,
Best.
I’ve just tried your suggestions but I am still a bit lost.
Before running go mod tidy && go mod vendor I also deleted the vendor folder to be sure the command was working as expected.
Docker file with version 3.21.1.
FROM heroiclabs/nakama-pluginbuilder:3.21.1 as builder
ENV GO111MODULE on
ENV CGO_ENABLED 1
WORKDIR /backend
COPY . .
RUN go build --trimpath --buildmode=plugin -o ./backend.so
FROM heroiclabs/nakama:3.21.1
COPY --from=builder /backend/backend.so /nakama/data/modules

The main.go with the new imports.
package main
import (
"context"
"database/sql"

... more imports for my RPC, Hooks, utils, etc methods
)
The go.mod file updated.

The errors I still face when running docker compose build --no-cache && docker compose up.

May am I missing something?
Something wrong with my environment perhaps?
I cannot imagine this being relevant but in case it’s needed:
go version go1.21.0 linux/amd64
For now, thank you very much for your help.
I don’t understand why your latest go.mod has different versions than the one I provided, if you use that it should have the correct dependencies pinned.
I suggest you delete your go.mod and go.sum and paste exactly what I gave you in a new go.mod, then retry to run go mod tidy && go mod vendor.
If the go.mod entries change versions again something’s incorrect.
Best.
Deleting the go.mod and go.sum helped fixing the situation.
Nakama now starts correctly, thank you very much!

After the go mod tidy && go mod vendor it still differs from yours.
module backend

require (
firebase.google.com/go/v4 v4.13.0
github.com/heroiclabs/nakama-common v1.31.0
github.com/mailersend/mailersend-go v1.5.1

google.golang.org/genproto/googleapis/api v0.0.0-20231212172506-995d672761c0
google.golang.org/genproto/googleapis/rpc v0.0.0-20231211222908-989df2bf70f3
google.golang.org/grpc v1.60.0
)
But nakama now starts so I would say the issue as been solved 
Thank you very much for your time Simon.
Best.
