AWS verifying SES identity from the wrong region - amazon-web-services

Question

I am trying to send an email from an AWS lambda function. However, I get this error
INFO MessageRejected: Email address is not verified. The following identities failed the check in region US-EAST-1: testemail#gmail.com, support#mydomain.com
Both identities are verified in ap-southeast-2 and the lambda function is in the same region. If I am running the function from ap-southeast-2 and all my email configurations, including SMTP point to ap-southeast-2, why is the verification happening in us-east-1
Below is my code
const SES = new AWS.SES({ region: "us-east-1" });
const sendEmail = async (event) => {
const params = getNotificationParams(event);
console.log(params);
if (!params || params.error) {
return Responses._400({
message: params.error,
});
}
try {
await SES.sendTemplatedEmail(params).promise();
return Responses._200();
} catch (err) {
console.log(err);
return Responses._500({ message: "Error sending email" });
}
};
module.exports = {
handler: sendEmail,
};

Answer 1

The mistake was that I specified the wrong region (us-east-1) during SES initialization. Here is the fixed code with ap-southeast-2
const SES = new AWS.SES({ region: "ap-southeast-2" });
const sendEmail = async (event) => {
const params = getNotificationParams(event);
console.log(params);
if (!params || params.error) {
return Responses._400({
message: params.error,
});
}
try {
await SES.sendTemplatedEmail(params).promise();
return Responses._200();
} catch (err) {
console.log(err);
return Responses._500({ message: "Error sending email" });
}
};
module.exports = {
handler: sendEmail,
};
