Report #69597

[bug\_fix] exec user process caused: exec format error

Build the image for the correct target architecture using the \`--platform\` flag, e.g., \`docker build --platform linux/amd64\`.

Journey Context:
A developer builds a Docker image on their new Apple Silicon \(M1/M2\) Mac, which defaults to building for the \`linux/arm64\` architecture. They push the image to a registry and deploy it to an AWS EC2 instance running standard AMD64 Linux. The container crashes immediately with 'exec format error'. The developer spends hours checking file permissions, entrypoint syntax, and shell formats, assuming the script has Windows line endings. The root cause is actually an architecture mismatch. The binary inside the container is compiled for ARM64, but the server's CPU is AMD64 and cannot execute the ARM64 instruction set. The fix is to explicitly build for the target deployment platform using \`docker buildx build --platform linux/amd64\`.
