Problem
Recently I came across an unusual error whilst working with C# Azure Functions. When the Function was executed, the console window showed the following error.
The ‘XXXXXX’ function is in error: Microsoft.Azure.WebJobs.Host: Error indexing method ‘XXXXXX ‘. Microsoft.Azure.WebJobs.Host: Can’t bind parameter ‘data’ to type ‘XXXXXX’.
I checked the Activity function parameter bindings however couldn’t see any obvious issue. However after some head scratching I eventually figured out the source of the issue …
In this post I’ll show you how to resolve this issue.
