sed: не могу прочитать (sed -i 's {{ExecutionRoleArn} ^' $ {ExecutionRoleArn} '^ g' $ {TaskDefinitionFile})

Question

при запуске .sh файла я получаю

sed: can't read error.

Настоящим мой код:

RoleName=$(aws cloudformation describe-stack-resource --stack-name "${RoleStackName}" --logical-resource-id ExecutionRole --output text | awk '{print $5}')
ExecutionRoleArn=$(aws iam get-role --role-name "${RoleName}" --output text | awk 'FNR==1 {print $2}')
sed -i 's^{ExecutionRoleArn}^'${ExecutionRoleArn}'^g' ${TaskDefinitionFile}
