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:

```auto
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`.

```auto

```

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.

```auto
FROM heroiclabs/nakama-pluginbuilder:3.20.0 as builder

ENV GO111MODULE on
ENV CGO_ENABLED 1

WORKDIR /backend
COPY . .
# COPY go.mod .
# COPY *.go .
# COPY vendor/ vendor/

RUN go build --trimpath --buildmode=plugin -o ./backend.so

FROM heroiclabs/nakama:3.20.0

COPY --from=builder /backend/backend.so /nakama/data/modules
COPY local.yml /nakama/data

```

This was my (working) `go.mod` before the packages.

```auto
module backend

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:

```auto
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:

```go
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](https://heroiclabs.com/docs/nakama/server-framework/go-runtime/go-dependencies/), 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`.

```auto
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
COPY local.yml /nakama/data

```

The `main.go` with the new imports.

```auto
package main
import (
	"context"
	"database/sql"
	"time"

	_ "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"

	"github.com/heroiclabs/nakama-common/rtapi"
	"github.com/heroiclabs/nakama-common/runtime"
	
    ... more imports for my RPC, Hooks, utils, etc methods
)

```

The `go.mod` file updated.

```auto
module backend
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 v0.20.0
	google.golang.org/api v0.180.0
	google.golang.org/genproto/googleapis/api v0.0.0-20240528184218-531527333157
	google.golang.org/genproto/googleapis/rpc v0.0.0-20240528184218-531527333157
	google.golang.org/grpc v1.64.0
)

```

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

```auto
nakama_backend | {"level":"error","ts":"2024-06-06T19:08:21.481Z","caller":"server/runtime_go.go:2820","msg":"Could not open Go module","path":"/nakama/data/modules/backend.so","error":"plugin.Open(\"/nakama/data/modules/backend\"): plugin was built with a different version of package google.golang.org/protobuf/internal/pragma"}

```

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!

```auto
nakama_backend | {"level":"info","ts":"2024-06-06T20:05:49.494Z","caller":"main.go:113","msg":"Nakama starting"}

```

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

```auto
module backend
go 1.21
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
github.com/minio/minio-go/v7 v7.0.67
golang.org/x/exp v0.0.0-20240604190554-fc45aab8b7f8
golang.org/x/oauth2 v0.15.0
google.golang.org/api v0.149.0
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
)

```

But nakama now starts so I would say the issue as been solved 🙂

Thank you very much for your time Simon.  
Best.
