From the docs:

Message size
The minimum message size is 1 byte (1 character). The maximum is 262,144 bytes (256 KB).

My guess is that the files you're trying to send are larger than 256KB, which is a hard limit for SQS messages in AWS.

The output HTTP content length exceeded 1662976 bytes suggests my guess might be correct.

The common pattern in this case is to upload the files to S3 and send a reference to the object through the Queue.
