Error in the Amazon DynamoDB Query node: JSON must not be null

KNIME Extensions

Hi,

When I query DynamoDB, I get this error where I have empty objects of JSON. Is that expected?

:blush:

Hi,
Is there an exception in the KNIME log that you could post? This error message alone unfortunately does not tell me much.
Kind regards,
Alexander

Hi,

No, there is nothing in the log. I get this error when I query for the inputs where there is a JSON attribute and the value is an empty object.

ERROR Amazon DynamoDB Query 0:1133 Execute failed: JSON must not be null

:blush:
