Я пытаюсь получить 3 столбца и применить условие к одному из параметров.
const result = await docClient.scan({
TableName: ridesTable,
AttributesToGet: ['from_city_id', 'from_date', 'Car_Cancellation'],
FilterExpression: 'Car_Cancellation = :one',
ExpressionAttributeValues : {':one' : 1}
}).promise()
но я получаю эту ошибку при запуске
{
"errorType": "ValidationException",
"errorMessage": "Can not use both expression and non-expression parameters in the same request: Non-expression parameters: {AttributesToGet} Expression parameters: {FilterExpression}",

}
Что означает эта строка?
Can not use both expression and non-expression parameters in the same request: Non-expression parameters: {AttributesToGet} Expression parameters: {FilterExpression}"
Как я могу go вокруг нее
