[GOWS] - Unable to start waha latests (2026.2.2) | CompileError: WebAssembly.Module(): Compiling function #99 failed: Wasm SIMD unsupported @+25226 |

[borin98]

Describe the bug

I am encountering a crash when trying to run the most recent gows version (2026.2.2) of the waha-plus image behind a Dokploy service. The container fails to start completely, throwing a CompileError indicating that Wasm SIMD is unsupported during the initial bootstrap process.

Version

Note: Since the container crashes on startup, I cannot call GET /api/version. However, based on the deployed image (devlikeapro/waha-plus:gows) and tags, the expected version is:

{
  "version": "2026.2.2",
  "engine": "GOWS",
  "tier": "PLUS"
}

Steps

To Reproduce Steps to reproduce the behavior:

1. Configure a docker-compose.yml using the devlikeapro/waha-plus:gows image.
2. Deploy the service via Dokploy on a KVM (QEMU) virtual machine.
3. Start the container.
4. Check the container logs to see the immediate CompileError during the whatsapp-rust-bridge initialization.

Expected behavior

The WAHA service should start up successfully and compile the WebAssembly modules without SIMD-related compilation errors.

Requests - Responses

Not applicable. The application crashes during the boot sequence before the API server can accept any requests.

Host Machine Details:
I am running this on a QEMU virtual machine. It's likely that the virtualized CPU (QEMU Standard PC _i440FX + PIIX, 1996_) is missing the necessary SIMD instruction sets required by the underlying WebAssembly modules in the gows engine.

• Static hostname: ubuntuserverprod1
• Virtualization: kvm
• Operating System: Ubuntu 22.04.4 LTS
• Kernel: Linux 5.15.0-170-generic
• Architecture: x86-64
• Hardware Vendor: QEMU
• Hardware Model: Hardware Model: Standard PC i440FX + PIIX, 1996

Can you guys help me and thanks for the suport !!

Hi!
The issue actually with NOWEB engine, we need to create separated docker images for each engine in the future :(

Let's try dev version!
You can force disable SIMD instruction using WHATSAPP_RUST_BRIDGE_FORCE_COMPAT=1 env variable (but it should handle it automatically 🤞 )

Make sure to select the engine via the environment variable - WHATSAPP_DEFAULT_ENGINE=GOWS:

• devlikeapro/waha-plus:dev
• devlikeapro/waha-plus:dev-arm

Hello and sorry for the wait.
I made a test right now and seems to work !

I'm using the env variables that you said:

• WHATSAPP_RUST_BRIDGE_FORCE_COMPAT: 1
• WHATSAPP_DEFAULT_ENGINE: GOWS

And the docker compose is using the image you recommended with dev tag

Just one question, on the next version that you guys release, Do I need to maintain this variables (WHATSAPP_RUST_BRIDGE_FORCE_COMPAT and WHATSAPP_DEFAULT_ENGINE) and the dev image ?
