Do not break foreach loop when API fails

Issue is inside custom connector ruby code.

Context: I have a list of companies in an array then I am using .each method to loop every company and then hitting an api call on every company.

Problem: Now one api call is failed for a company and code breaks. I don't want code to break, instead I want loop to continue as we use try catch in many languages to prevent breaking of loop. How to acheive the same in Custom Connector SDK using ruby.

Ruby exception handling is unfortunately also not supported in the SDK-Code.

There is no support for exception handling so I have move this code on the recipe level and then I used repeat action in a parent recipe on my company array and then every action goes to a child recipe where I use monitor block of recipe to handle exception from API. Then I move every error into lookup table.

My API call is as below:

company_ids.each {
                    |company_id|
                    puts("company_id: #{company_id}")
                    companyobject = post("#{base_url}/api/v2/labor-model/location/#{company_id}/run").payload(start:start_unix, end:end_unix).headers("Authorization": auth_header).
                    after_error_response(400, 401, 404, 417, 500) do |code, body, header, message|
                        error("#{message}: #{body}")
                    end
                    puts("companyobject: #{companyobject}")
                }

Hey @bhavesh-patel,

I think this page on ruby loops could be helpful for you: https://www.tutorialspoint.com/ruby/ruby_loops.htm

You can also find more variations of 'each' here: https://docs.workato.com/developing-connectors/sdk/sdk-reference/ruby_methods.html#each

Please let me know if you find your solution within those pages!

Cheers,
Meghan

I'm not sure if begin/rescue or catch/throw are supported in a custom connector, but you should give them a try. They aren't supported in the Ruby recipe connector (I tried and confirmed with Workato support) but the connector SDK tends to have broader Ruby support.

https://www.geeksforgeeks.org/ruby-exception-handling/

Here's an example:

companies.each { | company | 
   x = {}

   begin
      x.split(';') # example that will throw error
      # put your API call here
   rescue
      puts "error is skipped"
   end
}

Ruby exception handling is unfortunately also not supported in the SDK-Code.
