Failed build due to grpc-api-types

[drdholu]

Hi everyone, I’m trying to implement issue #9089 and I’m running into a build error when compiling the Rust binaries for running tests.

Here’s the error snippet:

error: failed to run custom build command for `grpc-api-types v0.1.0 (https://github.com/juspay/connector-service?rev=142cb5a23d302e5d39c4da8d280edababe0691fe#142cb5a2)`

Caused by:
  process didn't exit successfully: `/home/paras/hyperswitch/target/debug/build/grpc-api-types-fccac6a812fb546e/build-script-build` (exit status: 1)
  --- stderr
  g2h: Incompatible dependency `axum`: expected `0.8.3`, found `0.8.4`

Command i ran:

cargo clippy --all-features -- -D warnings

Environment details:

• Machine: Lenovo LOQ
• Local development with Docker Compose

Got the same error when setting up local Rust Environment using WSL

Has anyone faced this issue before or know how to resolve the version mismatch with axum?

[whatsupsumit]

You've run into a classic dependency conflict. One part of your project (grpc-api-types) strictly requires axum version 0.8.3, but another dependency pulled in a newer version (0.8.4), causing the build to fail.

Here’s how to fix it by forcing your project to use the correct version.

The Permanent Fix
The best way to solve this for you and your team is to add a patch to your main Cargo.toml file. This tells Cargo to override the dependency version for the entire project.

Just add this to the end of your Cargo.toml:

Ini, TOML

[patch.crates-io]
axum = { version = "0.8.3" }
Then, try building again. This should resolve the issue permanently.

The Quick Fix
If you just want to get it working quickly on your machine, you can run this command to update your lock file to the precise version needed:

Bash

cargo update -p axum --precise 0.8.3
This command specifically targets the axum package and locks it to version 0.8.3.
