Function returns a 500 server error, function log says req_body being accessed before it is set

Successfully deployed the http trigger sas token generator to azure but when I test it using the azure test utility the console gives the following error.

2019-06-07T12:11:57.118 [Information] Executing 'Functions.GLNorton287Func' (Reason='This function was programmatically called via the host APIs.', Id=00cf0c14-75be-4070-b48e-292dfcefd3ae)

Any ideas why this is happening?

Thank you

I add some exception handing for this. Here is diff

Please use the latest function - http-trigger-blob-sas-token and try again
