Lex 无法访问 Lambda 函数

Question

I am getting this error when i try to add a lambda function for fulfillment in lex:

Lex is unable to access the Lambda function arn:aws:lambda:us-east-1:843706464800:function:OrgbotFulfillment in the context of intent arn:aws:lex:us-east-1:843706464800:intent:Add:$LATEST. Please check the resource-based policy on the function

This error is occurring for only one intent out of the ten intents my bot has, while the same fulfillment function is being used for all of them.Where is the cause and How can I resolve this?

Answer 1

The List comes from your lambdas in the same region. AWS Lambda needs access permission to Lex.

aws lambda add-permission --function-name <lambda_name> --statement-id chatbot-fulfillment --action "lambda:InvokeFunction" --principal "lex.amazonaws.com"
