Hi
i require some guidance on how to deal with (e.g. catch) json parsing exceptions when making retrofit api calls using arrow retrofit apdapter

[Tower Guidev2]

my calling code resembles this...

private suspend fun actualWork(): Either<Any, Any> = either {
    val networkData = repository.pharmaDocumentsSearch(options = mapOf("text" to "*", "limitation.count" to "100")).tapLeft { networkError -> consumeNetworkError(workerName, networkError) }.bind()
    Either.catch { repository.database.documentSearchItemDAO().insertAsync(manufacture(networkData)) }.tapLeft { databaseError -> consumeDatabaseError(workerName, databaseError) }.bind()
}

and my error processing function is

fun consumeNetworkError(caller: String, exception: CallError) {
    when (exception) {
        is HttpError -> doLogging { "$caller Network Http error :: ${exception.code} ${exception.message} ${exception.body}" }
        is IOError -> doLogging(exception.cause) { "$caller Network IO error" }
        is UnexpectedCallError -> doLogging(exception.cause) { "$caller Unexpected Network error" }
    }
}

which all works really nicely

however when a json parsing exception occurs i do not log any errors
my actualWork function fails silently

here is the repositiry function

override suspend fun pharmaDocumentsSearch(headers: Map<String, String>, options: Map<String, String>): Either<CallError, DocumentsSearch> =
    withContext(NETWORK) { service.pharmaDocumentsSearch(headers = HEADERS, options) }

so i need to "wrap" the network call in an outer

Either.catch { }
