s3Sync operation cause IllegalLocationConstraintException

[dengmingtong]

Hello,
I am using serverless s3Sync to copy local file to aws s3 in HongKong(ap-east-1) region, I got below error:

IllegalLocationConstraintException: The ap-east-1 location constraint is incompatible for the region specific endpoint this request was sent to.
at Request.extractError (/home/ec2-user/environment/gcr-solutions/service-workbench-on-aws/node_modules/.pnpm/[email protected]/node_modules/aws-sdk/lib/services/s3.js:837:35)

Does serverless s3Sync support AWS HongKong region?
If yes, how can I config serverless.yml to fix this issue?

Thanks
Mingtong
