[SOLVED] Python Zeep- 'Input string was not in a correct format'

Python Zeep- 'Input string was not in a correct format'

I am using zeep to interact with a webservice in Python; I have everything mostly working but am having trouble getting certain fields set. The issue appears to be with the input string, it is attempting to convert it to 'Text' but is failing. I am a bit lost and do not know how to accomplish this, I've had no luck so far. I'm assuming I have to do some sort of conversion but I am not sure how to do this.

For context, this is what I am trying to set. The field(Voucher ID in this case) is found but the FieldValue is not formatted correctly. Here is a rundown of that code.

        #Set fields
        voucher_id.FieldId = 15   #Voucher ID
        voucher_id.FieldValue = "test"

        #Array
        field_array =  factory.ArrayOfFieldWithValue()
        field_array['FieldWithValue'].append(voucher_id)

        #Call service function to add document info, which causes the exception

And here are the exception messages.

I have tried formatting the FieldValue in a couple of other basic ways but always receive the same error.

Solution

Solved by using zeep.xsd.AnyObject to transform Python type to xsd type.

voucher_id.FieldValue = zeep.xsd.AnyObject(zeep.xsd.String(), 'zeep_test')
