Possible error in the SparkJson library?

Firmware Libraries
1

I have code that uses the SparkJson library. I have successfully compiled and loaded this code from the Web IDS onto my Argon device.

I am moving to VSCode, so I created a new project and used the VSCode/Particle tools to install the libraries locally.

When I CLOUD compile (tried with 2.0.0-rc2 and with 1.5.2), I get this warning/problem.

Problem:

Dynamic.JsonBuffer.h lib/SparkJson/src
deleting object of polymorphic class type 'ArduinoJson::DynamicJsonBuffer' which has non-virtual destructor might cause undefined behavior [-Wdelete-non-virtual-dtor]

Output Error:

lib/SparkJson/src/././DynamicJsonBuffer.h: In destructor 'ArduinoJson::DynamicJsonBuffer::~DynamicJsonBuffer()':
lib/SparkJson/src/././DynamicJsonBuffer.h:20:33: warning: deleting object of polymorphic class type 'ArduinoJson::DynamicJsonBuffer' which has non-virtual destructor might cause undefined behavior [-Wdelete-non-virtual-dtor]
   20 |   ~DynamicJsonBuffer() { delete _next; }

I am not sure how to deal with this. Stackoverflow has a couple threads with this error, but they basically say “Don’t use this class”.

As this works on the cloud, but not with the cloud compile command on VSCode.

Also… I just tried to do a local compile and it appears to have completed successfully. But I have not tested that code on a device yet.

2

Have you tried using the JsonParserGeneratorRK library instead?

3

That’s a warning, and won’t prevent the build from completing. There’s likely something else that’s an error in the build output.

4

I think I have used that in another project; I was hoping not to have to really dig into this code, since it compiles fine locally.

5

Yeah, that’s what I figured. I think the actual error may be getting cut off in the output…
