AWS Lambda Runtime.UserCodeSyntaxError: Syntax error in module 'salesAnalysisReport': invalid syntax

May 7, 2022

I am working on AWS Solutions Architecting Module 13 Challenge Lab. I have written the following code in my AWS Lambda SalesAnalysisReport function’s salesAnalysisReport.py file :

    response = snsClient.publish(
        TopicArn = arn:aws:sns:us-east-1:507782174659:SalesReportTopic,
        Subject = 'Daily Sales Analysis Report',
        Message = message.getvalue()    
    )

I am running default hello-world test case and getting the following error message :

[ERROR] Runtime.UserCodeSyntaxError: Syntax error in module 'salesAnalysisReport': invalid syntax (salesAnalysisReport.py, line 129)
Traceback (most recent call last):
File "/var/task/salesAnalysisReport.py" Line 129
TopicArn = arn:aws:sns:us-east-1:507782174659:SalesReportTopic,END RequestId: 5bb30f77-0fae-453a-8f56-b89cdbd064a8

I am using Python 3.8 as directed in lab instructions.

I would like to know the cause of error so that I can resolve it

P.S. – Line 129(error causing line) is

TopicArn = arn:aws:sns:us-east-1:507782174659:SalesReportTopic,

I tried putting the value of TopicArn in double quotes and then using that for TopicArn but that didn’t work.

>Solution :

You need to enclose it in single quotes, so it is a string as required by Boto3.

Try:

response = snsClient.publish(
        TopicArn = 'arn:aws:sns:us-east-1:507782174659:SalesReportTopic',
        Subject = 'Daily Sales Analysis Report',
        Message = message.getvalue()    
)
