I have been having isues trying to get past this error on my VSCode.
I will appreciate any help.
Thank you.

I am trying to try my hand on asset tracking project built on AWS.

$ chmod +x deploy_cloudformation.sh && export AWS_REGION=us-east-1 && ./deploy_cloudformation.sh Deploying kinesis data stream template for sample app. ./deploy_cloudformation.sh: line 16: aws: command not found Retrieving TrackingAndGeofencingSampleKinesisDataStreamARN from the created CloudFormation stack. ./deploy_cloudformation.sh: line 28: aws: command not found Error: Failed to retrieve TrackingAndGeofencingSampleKinesisDataStreamARN from CloudFormation stack.

This is the deploy_cloudformation.sh:

`*#!/bin/sh

Configurable variables

TrackerName=”SampleTracker”

SAR application id for kinesis-stream-device-data-to-amazon-location-tracker app

ApplicationId=”arn:aws:serverlessrepo:us-east-1:003883091127:applications/kinesis-stream-device-data-to-amazon-location-tracker”

if [ -z “$AWS_REGION” ]; then
echo “Error: AWS_REGION is not set. You may set the environment variable with this command: ‘export AWS_REGION=us-east-1’.”
exit 1
fi

echo “Deploying kinesis data stream template for sample app.”

aws cloudformation deploy
–template-file src/cfn_template/kinesisResources.yml
–stack-name TrackingAndGeofencingSampleKinesisStack
–region ${AWS_REGION}

echo “Retrieving TrackingAndGeofencingSampleKinesisDataStreamARN from the created CloudFormation stack.”

Retrieve the KinesisDataStreamARN output from the deployed stack

KinesisDataStreamARN=$(aws cloudformation describe-stacks
–stack-name TrackingAndGeofencingSampleKinesisStack
–query “Stacks[0].Outputs[?OutputKey==’TrackingAndGeofencingSampleKinesisDataStreamARN’].OutputValue”
–output text
–region “${AWS_REGION}”)

Check if KinesisDataStreamARN was retrieved successfully

if [ -z "$KinesisDataStreamARN" ]; then echo "Error: Failed to retrieve TrackingAndGeofencingSampleKinesisDataStreamARN from CloudFormation stack." exit 1 fi

Check if ChangeSetId was captured successfully

if [ -z "$ChangeSetId" ]; then echo "Error: Failed to capture ChangeSetId from the create-cloud-formation-change-set output." exit 1 fi

Sleep for 5 seconds to allow the change set to be created.

sleep 5
Changes=$(aws cloudformation describe-change-set –change-set-name “$ChangeSetName” –stack-name “$SarStackName” –query “Changes” –output text)
echo “$Changes”
if [[ -z “$Changes” || “$Changes” = “None” ]]; then
echo “No changes to deploy. Stack serverlessrepo-$SarStackName is up to date.”
else
echo “Executing change set: $ChangeSetId”

Retry logic for executing the change set to avoid calling the execute API too fast.

` max_attempts=5
attempt=1
while [ “$attempt” -le “$max_attempts” ]; do
echo “Attempt $attempt of $max_attempts: Executing change set $ChangeSetId”

execute_output=$(aws cloudformation execute-change-set --change-set-name "$ChangeSetId" --region "$AWS_REGION" 2>&1)
execute_status=$?

if [ "$execute_status" -eq 0 ]; then
  echo "Change set executed successfully: $ChangeSetId. You can go to CloudFormation's console to monitor the deployment progress."
  break
fi

if [ "$attempt" -eq "$max_attempts" ]; then
  echo "Maximum execution attempts reached, failing execution."
  exit 1
fi

((attempt++))
sleep 1

done

sleep 2 # Wait for 2 seconds for the previous stack deployment to finish the tracker creation.

echo “All deployments complete!”*`

I have tried to copy templates for creating CloudFormation, but i seem not to understand.

If anyone can point me to a youtube video that can help, i will appreciate.
