I was getting the same error as above. Found out since I was using index on my table, I had to specify...

response = table.query(
IndexName='clientId-meetingDate-index',
KeyConditionExpression=Key('clientId').eq('abc') & Key('meetingDate').gte('2022-05-05')
)

Of course change to your index, and attribute values, but after adding IndexName, all worked well.
