Lambda function can't push messages to sqs

I have a lambda function with an exacution role with this policies:

• AWSLambdaBasicExecutionRole ("logs:CreateLogStream", "logs:PutLogEvents")
• a custom policy ({ "Effect": "Allow", "Action": [ "sqs:SendMessage", "sqs:ListQueues" ], "Resource": [ "arn:aws:sqs:myqueue" ] })
• AWSCodeCommitReadOnly the my sqs queue has aan access policy:

{ "Sid": "AllowLambdaAccess", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::myLambdaServiceRole" }, "Action": "SQS:SendMessage", "Resource": "arn:aws:sqs:mySqsQueue" }

the lambda function and the queue are in the same region. No vpc configured for the lambda function. proplem is lambda times out and can't push messages to sqs

code for lambda is pretty standard:

const { SQSClient, SendMessageCommand } = require('@aws-sdk/client-sqs');
const sqsClient = new SQSClient({ region: 'us-east-1' });
const queueUrl = 'https://sqs.us-east-1.amazonaws.com/XXXXXXXXXXX/MySqsQueue';

const messageParams = {
                QueueUrl: queueUrl,
                MessageBody: JSON.stringify({MY OBJECT DEFINED HERE})
            };
            try {
                const command = new SendMessageCommand(messageParams);
                await sqsClient.send(command);
                console.log('Message sent to SQS queue successfully.');
            } catch (error) {
                console.error('Error sending message to SQS:', error);
            }

any idea what I am doing wrong?
