Error: DynamoDB Invalid UpdateExpression Syntax Error Token
Answered by Rafal Wilinski
Solution
The 'UpdateExpression' parameter you're using in your request is incorrect and could not be parsed.
Troubleshooting steps:
- Make sure you're not using one of the reserved keywords.. Use 'ExpressionAttributeNames' to replace conflicting attribute names with proxies.
- Make sure that none of your attribute names begins with underscore (_), it cannot be the first character.
- Use libraries like dynoexpr which might prevent creating silly mistakes in UpdateExpressions.
