Rescuing BubbleWrap::JSON::ParserError

[Neil]

Hi all

If the web API is inaccessible and BW attempts to make a request, the app crashes with a BubbleWrap::JSON::ParserError. Adding a begin rescue doesn't seem to prevent the app from crashing. E.g:

begin

  BW::HTTP.post(url, payload: payload) do |response|

    if response && response.body

      data = BW::JSON.parse(response.body.to_str)

      # use data

    end

  end

rescue BubbleWrap::JSON::ParserError => exception

  return nil

end

Is there some way to catch & raise an error from BW here? Or is BW able to check if the URL will respond in the first instance (preventing the subsequent ParserError)?

Thanks in advance

I think you may perform the rescue from inside the callback, i.e.:

  BW::HTTP.post(url, payload: payload) do |response|

    if response && response.body

      begin

        data = BW::JSON.parse(response.body.to_str)

      rescue BubbleWrap::JSON::ParserError => exception

        return nil

      end

      # use data

    end

  end

Hi Andy. The error still isn't being caught:
