Citizen profile PutItem calls fail while CloudWatch shows ProvisionedThroughputExceeded on the table. Developers suspected a null-pointer in app code. What does the evidence indicate?
Select an answer to reveal the explanation.
Short Explanation
ProvisionedThroughputExceeded is DynamoDB waving a capacity flag, not your app tripping over a null. Separate throttle error codes and metrics from code bugs before you rewrite the handler.
Full Explanation
ProvisionedThroughputExceeded is DynamoDB’s signal that provisioned (or effective) capacity was exceeded for the request pattern. Developers should treat that error code and related CloudWatch throttle metrics as a capacity/limit issue distinct from application null-pointer defects. Misattributing throttles to SDK null handling, API Gateway renames, or S3 Transfer Acceleration delays the correct fix.
