Newtonsoft.Json.JsonReaderException thrown when ru

Question

I created a queue trigger template of Azure function v2 in VS2017. When I ran the project locally, the function runtime started successfully. But when I created a message in the queue, VS downloaded a JsonSerialization.cs file and pointed out the error.

Details of default Exception settings:

It's a template generated by VS, so there seems no code issue like what I have found in other posts.

What I have tried:

• Publish the project to Azure, works.
• Run the project with function core tool(Cli) installed by npm, also works.

I guess the problem is related to the function Cli used by VS. But its runtime version is 2.0.11651.0, same as the one installed by npm.

Have anyone met this before or got any idea? Thanks in advance.

Answer 1

This exception is internal and should be caught by the runtime. Feel free to ignore it in exception settings, and then everything should just work.
