Cannot read property 'matcherResult' of undefined

[vivacenontroppo]

Clear installation of the package, basic setup and all I got on tests that that passes is Cannot read property 'matcherResult' of undefined

package.json

let testError = error.matcherResult

this code is used in Jest
I'm not sure what is it equal to other test frameworks such as jasmine

I have to comment out these block of code in order to not introduce the error as above

let testError = error.matcherResult
            .message()
            .replace(
                /[\u001b\u009b][[()#;?]*(?:[0-9]{1,4}(?:;[0-9]{0,4})*)?[0-9A-ORZcf-nqry=><]/g,
                ""
            );

footer: testError.toString(),

any solution to this? matcherResult undefined for me as well.

[vivacenontroppo]

@pmerwin for me it was just switching to @slack/web-api and writing my own reporter, which works great with this package. The one I described above, as you can see noone cares.

Yeah that's what I am working on now, thanks !

@pmerwin I wrote a quick guide as an answer on stack, just FYI, maybe it can help:

[carmenmitru]

@vivacenontroppo @pmerwin @anhhanuman @vivacenontroppo I published a new version of the npm package.

[andisan86]

I am still getting the same issue with version 2.0.8. Any hints to get around this?

Sorry I did not realise that there was version 2.0.9. This error was not reproducible anymore for me in version 2.0.9

[vivaan007]

It fails for me even with version 2.0.9
However, commenting out error.matcherResult line and the attachment code, it works fine showing the status.

@carmenmitru Below is the results value in aftertest:
