Is it GetRecordField that's null, or the .Values that's null?

Seems to be rec.GetRecordField(Constants.Form.AnswersJsonField) 

the value i am passing is the name of the field setup in contour its called Answers i just tried lower casing it no joy.

Hmm just updated code to

            using (var recordStorage = new RecordStorage())

            {

                var rec = recordStorage.GetRecord(new Guid(recordId));

                var form = new FormStorage().GetFormFromRecordId(rec.Id);

                Guid answerFieldGuid = (from f in form.AllFields where f.Caption == Constants.Form.AnswersJsonField  select f.FieldTypeId).FirstOrDefault();

                var rs = new RecordService(rec);

                rs.Open();

                rec.GetRecordField(answerFieldGuid).Values.Clear();

                rec.GetRecordField(answerFieldGuid).Values.Add(new List<string> { formJson });

                recordStorage.UpdateRecord(rec, form);

                recordStorage.UpdateRecordXml(rec, form);

                rs.Submit();

                rs.Dispose();

            } 

still no joy get Object reference not set to an instance of an object on line rec.GetRecordField(answerFieldGuid).Values.Clear();

I think you need to pass in the Guid instead, looking at some old Contour API code on one of my sites (although its a slightly different part of the API).

Passed in guid still get null grrrr

Odd. I'll have a dig through oneof my old sites when I get home tonight, I might have some example code somewhere I think.

awesome many thanks. bit more information the user fills in form that takes them to another page. On that page is another form but this is not contour its a radio button matrix set of questions with weighting values could have done it with my own field type etc but no time so I did this instead. When they submit this i take the values convert to json string and set to hidden field called answers. I suspect that becuase on the first form the field was blank it does not end up in contour.

Right bit more progress with this. I know what the issue is. If you have a blank field then in the record values its not there. So I have work around in my hidden field I have added a default value now I can get the field and update it. However when I save I get error "Object must implement IConvertible."

My code now looks like

string formJson = GetFormJson();

            using (var recordStorage = new RecordStorage())

            {

                var rec = recordStorage.GetRecord(new Guid(recordId));

                var form = new FormStorage().GetFormFromRecordId(rec.Id);

                var rs = new RecordService(rec);

                rec.GetRecordField(Constants.Form.AnswersJsonField).Values.Clear();

                rec.GetRecordField(Constants.Form.AnswersJsonField).Values.Add(new List

                recordStorage.UpdateRecord(rec, form);

                recordStorage.UpdateRecordXml(rec, form);

                rs.Submit();

                rs.Dispose();

            }          

Full stack trace is

System.InvalidCastException was caught

  HResult=-2147467262

  Message=Object must implement IConvertible.

  StackTrace:

       at Umbraco.Forms.Data.Storage.RecordStorage.UpdateRecord(Record record, Form form)

Any ideas?

Cool, was going to say was the value empty, had a similar issue with my code by the look of it, as I check for nulls on them first. I haven't ever run into the error you're getting now though, sorry!

This may be a bit off topic but I'm desperate.

I've made my own Contour Workflow and need to null check some fields before executing certain code.

Any idea how to check for a null value of if you dont have the id and only the name as a string?
for example record.GetRecordField("Your email") always gives me the exception {"Sequence contains no elements"} so I cant figure out how to null check the value.

record.RecordFields.Any(x=> x.Value.Field.Caption == "Your email")
