Render trace in JsonErrorRenderer

[maiermic]

In Slim 3, the trace of an exception is rendered in JSON response (see Slim/Handlers/PhpError::renderJsonErrorMessage). In Slim 4, the field trace is missing (see Slim/Error/Renderers/JsonErrorRenderer:: formatExceptionFragment). Was this change intentional? Otherwise, please add the field trace again.

You can make your own error renderer or extend an existing renderer.

Thanks, that's what I did as a workaround. The easiest way would be to extend JsonErrorRenderer and override the method formatExceptionFragment, but it is private. Hence, you have to copy the code and modify it.

Anyhow, it is inconsistent if JsonErrorRenderer does not include the trace, but others do, see:

• Slim/Error/Renderers/HtmlErrorRenderer
• Slim/Error/Renderers/PlainTextErrorRenderer

I'm closing this as resolved.

@l0gicgate I wouldn't consider this as resolved. See my question:

Was this change intentional?

I still consider it as an accidental breaking change, i.e. a bug. All other renderers still render the trace. Only JsonErrorRenderer is missing it after the upgrade from Slim 3 to 4. I have not found any explanation for this change. Not in the commit messages, the issues or the changelog.
