How can i configure my aws credentials in shared credentials file for github action

I am trying to deploy the ci/cd pipeline for ECR in AWS.

It will push/pull the image from ECR

We are trying to migrate the azure pipeline to GitHub actions pipeline

When I try to implement the pipeline I am facing the below error,

[05:25:00] CredentialsProviderError: Profile Pinz could not be found or parsed in shared credentials file.

Here is my workflow YAML file,

on:
  push:
    branches: [ main ]

name: Node Project `my-app` CI on ECRjobs
jobs:
  deploy:
    name: Deploy
    runs-on: ubuntu-latest
    
    steps:
    - uses: actions/checkout@v2
    - name: Use Node 14.17.X

      uses: aws-actions/configure-aws-credentials@v1

        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: us-east-2

    - name: Login to Amazon ECR
      id: login-ecr
      uses: aws-actions/amazon-ecr-login@v1

    - name: Build, tag, and push the image to Amazon ECR
      env:
        ECR_REGISTRY: ${{ steps.login-ecr.outputs.registry }}
        ECR_REPOSITORY: test-pinz-api
        IMAGE_TAG: latest
      run: |
        gulp publish --profile-name development

Using gulp we publish the environment using below config file,

{
    "apiDomainName": "domain",
    "assetsDomainName": "domain",
    "awsProfile": "Pinz",
    "bastionBucket": "bucketname",
    "corsDomains": ["domain"],
    "dbBackupSources": ["db source", "db source"],
    "dbClusterIdentifier": "cluster identfier",
    "designDomainName": "domain",
    "lambdaEcr": "ecr",
    "snsApplication": "sns",
    "snsServerKeySecretName": "name",
    "stackName": "name",
    "templateBucket": "bucketname",
    "userJwtPublicKey": "token",
    "websiteUrl": "domain",
    "wwwDomainName": "domain",
    "wwwEcr": "ecr repo"
}

I couldn't find the shared credential file where the AWS credentials are saved.

I don't have any idea where the below profile configured

"awsProfile": "Pinz"

I analyzed all project files but couldn't get the shared credentials

I analyzed this in many documents and ended up with some nearer answers but couldn't get the exact answer. below it says ~/.aws/credentials. but how does above JSON file get the credentials from there?

https://docs.aws.amazon.com/sdk-for-javascript/v2/developer-guide/loading-node-credentials-shared.html

Honestly, this ECR pipeline deployment is my first time. Also, I didn't get proper KT about the process as well. I think am almost done on this but for gulp it shows this error

Can anyone please guide me to where will be this shared credentials file? If not how can I configure the AWS credentials to authenticate with AWS?
