Error while testing quickstart function deployment in readme on AWS-Lambda

[prasoonpatidar]

I am trying to create a aws-lambda deployment by following example mentioned in readme file. The build and deployment happened successfully. But when I try to test it with curl command provided. It returns the following.

I dig deeper by looking at Cloudwatch logs, and while loading the bento model (bento_service = load("./")), it is trying to create a directory for loading models (I do not understand this part clearly), while lambda only has a read-only file system. Here is the detailed log output from cloudwatch.

[ERROR] OperationFailed: operation failed, [Errno 30] Read-only file system: b'/home/bentoml/bento/models/iris_clf/latest'
