New line causes ValidationException (potential race condition)

[l1x]

Describe the bug

The following code results in an exception:

fg = FeatureGroup(
    name="hello", sagemaker_session=feature_store_session
)
fg.put_record([
    FeatureValue('id', '2'),
    FeatureValue('data', 'test\n'),
    FeatureValue('EventTime', '0.0')
])

The exception:

ClientError: An error occurred (ValidationException) when calling the PutRecord operation: 1 validation error detected: Value 'test
' at 'record.2.member.valueAsString' failed to satisfy constraint: Member must satisfy regular expression pattern: .*

To reproduce

See above.

Expected behavior

Probably have an exception saying new line characters are not allowed instead of saying a regexp check failed.
