What's Causing This Error
This error may occur due to multiple developers introducing bugs. For example, you may get this error if the object variable (parentparams
) you refer to in the query()
method has not been defined.
// where is parent params defined? if its missing, you will get the "not defined" error await documentClient.query(parentparams).promise();
Solution: Here's How To Resolve It
To resolve the error, define a constant variable named parentparam
of type object
that you can use to declare the query parameters.
// define the parent params object const parentparams = { ExpressionAttributeValues: { ':s': 2, ':e': 9, ':topic': 'PHRASE' }, KeyConditionExpression: 'Season = :s and Episode > :e', FilterExpression: 'contains (Subtitle, :topic)', TableName: 'EPISODES_TABLE' }; // parentparams is defined this time, no error await documentClient.query(parentparams).promise();
