Kinesis saveRecord failing with null pointer exception

[meavydev]

Describe the bug
Rather than the ACE exception, it looks like the internal code is failing with a null pointer:
05-24 16:33:50.234 12079 7514 E AndroidRuntime: java.lang.NullPointerException 05-24 16:33:50.234 12079 7514 E AndroidRuntime: at java.io.FileOutputStream.<init>(FileOutputStream.java:227) 05-24 16:33:50.234 12079 7514 E AndroidRuntime: at com.amazonaws.mobileconnectors.kinesis.kinesisrecorder.FileManager.newOutputStream(FileManager.java:115) 05-24 16:33:50.234 12079 7514 E AndroidRuntime: at com.amazonaws.mobileconnectors.kinesis.kinesisrecorder.FileRecordStore.tryInitializeWriter(FileRecordStore.java:121) 05-24 16:33:50.234 12079 7514 E AndroidRuntime: at com.amazonaws.mobileconnectors.kinesis.kinesisrecorder.FileRecordStore.put(FileRecordStore.java:80) 05-24 16:33:50.234 12079 7514 E AndroidRuntime: at com.amazonaws.mobileconnectors.kinesis.kinesisrecorder.AbstractKinesisRecorder.saveRecord(AbstractKinesisRecorder.java:100) 05-24 16:33:50.234 12079 7514 E AndroidRuntime: at com.amazonaws.mobileconnectors.kinesis.kinesisrecorder.KinesisRecorder.saveRecord(KinesisRecorder.java:240)
To Reproduce
It is difficult to say what is triggering it, but it is failing after running for a few hours.

Which AWS service(s) are affected?
Kinesis

Expected behavior
No crash or an ACE exception.

Environment Information (please complete the following information):

• AWS Android SDK Version:
  com.amazonaws:aws-android-sdk-kinesis:2.18.0
  other AWS SDKs are 2.19.0

• Device: Pixel 3A

• Android Version: 11

• Specific to simulators: No

Also seeing a related submitAllRecords error, but this is returning the AmazonClientException :

Having noticed an update AWS SDK of 2.26.0, we still see exceptions:
