AWS ECS exec /usr/local/bin/docker-entrypoint.sh: exec format error

I am pretty new to this Docker world and I am trying to deploy an image (nodejs-typescript service) from aws ECR to aws ECS but when I create the service inside the cluster this error appears and the taks never gets running:

exec /usr/local/bin/docker-entrypoint.sh: exec format error

My Dockerfile looks like this:

FROM node:lts-alpine

WORKDIR /usr/app

COPY package*.json ./
COPY tsconfig*.json ./

RUN yarn install --quiet

RUN yarn global add pm2

COPY . .

RUN yarn build

CMD ["pm2-runtime", "build/src/localServer.js"]

It is working fine on my pc when I build the image and run it:

(base) MacBook-Pro api % docker run -it -p 3000:3000 api-dev                                    
2022-12-06T15:35:27: PM2 log: Launching in no daemon mode
2022-12-06T15:35:27: PM2 log: App [localServer:0] starting in -fork mode-
2022-12-06T15:35:27: PM2 log: App [localServer:0] online
Connected to my_mongo_db_cluster
🚀  Server ready at: http://localhost:3000/

The task definition is running on Linux/X86_64.

Any suggestions or tips to find out what is the problem? Thanks!

EDIT: when I add an ENTRYPOINT to my Dockerfile like this

# same steps

COPY . .

RUN yarn build

ENTRYPOINT ["pm2-runtime", "build/src/localServer.js"]

it throw this error exec /usr/local/bin/pm2-runtime: exec format error. The same happens when I change pm2-runtime to node

# same steps

COPY . .

RUN yarn build

ENTRYPOINT ["node", "build/src/localServer.js"]

Hope it helps.

I found out what was the problem. It was my Apple M1 chip doing its incompatibility magic. For those who has the same problem, just adding the platform --platform=linux/amd64 in your Dockerfile seems to solve the problem:

FROM --platform=linux/amd64 node:lts-alpine
