Hello,

Do you have the possibility to create an instance of ClassA or ClassB when calling the service (based on some input parameters) and call the SomeMethod method from the correspondent class instance? It will call the method implemented in the correspondent class and your task will be achieved.

Hello,

It seems that the issue is that you are passing the first item read in the "Read bank account" element of the process (see [#Read bank account.First ite... in the "PartyAcctRelType" collection property settings from your screenshot). What should be done is modifying the "Read bank account" element and reading collection of records there, not the very first element from it:

And pass an actual collection of data read. This should work properly.

Greetings, 

 

Possibly only through Oauth.

Hi!

Have you made any recent changes to the webservice endpoint? Also, have there been any recent changes to the Creatio instance?

Looking forward to hearing from you!

Alla Blinova,

Hi Alla,

I haven't made any changes to the webservice endpoint since I have created it.



The process was:

1. Create the C# code object in the advanced settings

2. Code the webservice function

3. Compile the package

4. Edit the classicUI section page source code (Adding button to call the webservice)

5. Complie the package once again

Also, there weren't any changes regarding my Creatio instance.

Few weeks ago I had done the same steps on a cloud trial version where it worked just perfectly.



*Edit: Typo

Thanks!

Then we would suggest trying to call the webservice with a different record or data set to see if the issue persists.

If the issue continues, then try the source code generation and full compilation as a potential solution.

Alla Blinova,

I have tried to recomplie the individual package, then all the other packages and also tried source code generation but I had no success.



However I had a saved package where I have used a similar webservice. I installed this package on a trial cloud environment then locally.

The webservice call worked both on cloud and on local environment.



After this I exported my package which has the reported problem regarding webservice and installed it on cloud and it still doesn't work there.

Is there a method to check whether I have all the requirements to call the webservice, or is it possible to compare the two webservice/package components?

Hi Alla,

I have been able to resolve the issue.

I tried to call [Creatio instance]/0/rest/[package name]/[function call] instead of [Creatio instance]/0/rest/[webservice class]/[function call].

Thank you for your help.

hi Prashant Jha

Creatio has its "JSON key parser" in a core assembly that works OOTB in the service section. Usually, it occurs in the Method & Body Parameters of a Web Service.



On looking at the exception, the input types are not matched here and one of the input types is Collection List.



Can we backtrack it by passing the parameters one by one? which means trying to send Parameter A, get the exception and then try passing Parameter A, and B to get the exception.



From the above information, I presume that the error lies in the below factors,

Body Parameter :

Key : “file”

Value : (Base64 data)

Hello,

This error could be due to incorrect handling of an array of parameters in the web service response (Result).

Try to remove parameter array from web service response.

Hi, take a look at this article, I believe that there you can find a piece of useful information. It is written for the Freedom UI page, however, in earlier versions, you can just use XMLHttpRequest for sending the request, wait for a response, and process it.

The link somehow is broken now.

Pascal,

Here you are - link

Hello,

Take a look at this conversation, it is very similar to your question.

Hello,

In order to process the collection inside a collection, you need to do the following:

1) In the process, create a new parameter and add values to it from the web server response:

2) In your script task, you need to proceed this parameter and get values from it.

Dmytro Vovchenko,

Thanks for the information shared.

We were able to achieve processing the multiple nested collection through the below script and insert the Parent/Child collection sequentially.

List<object> deliveryItem = new List<object>();
List<object> lineItem = new List<object>();
var serviceOut = Get<ICompositeObjectList<ICompositeObject>>("Output");
 
foreach(ICompositeObject chall in serviceOut){
	if(chall.TryGetValue<ICompositeObjectList<ICompositeObject>>("Challan" , out ICompositeObjectList<ICompositeObject> curChallan)){
		foreach(ICompositeObject _challan1 in curChallan){
				curChallan1.TryGetValue<string>("Driver_contact_no" , out string Driver_contact_no); 
				deliveryItem.Add(Driver_contact_no);
 
				if(_challan1.TryGetValue<ICompositeObjectList<ICompositeObject>>("Lines" , out ICompositeObjectList<ICompositeObject> curLines)){
					foreach(ICompositeObject _Lines1 in curLines){
							_Lines1.TryGetValue<decimal>("Secondary_quantity_ctn" , out decimal Secondary_quantity_ctn); 
							lineItem.Add(Secondary_quantity_ctn);
				}	
			}
		}
	}
}

Also, we can utilize this without performing the Step 1 of Creating Nested Parameter Collection in Parameters of Business Process. Since the Web-Service already has the response parameter of same. But the parameter name from Webservice is always with a suffix _OUT





Iteration of Composite object collection is done through by following the Type<> in below Interface

ICompositeObjectList<TObject>

Interface ICompositeObject

Hi Pascal,

This can be achieved via OOTB no-code tools of Business Processes.

The response collection of an API can be sent to a sub-process with parameter filled and it can be set to run sequentially so that all the response data will be successfully inserted into the table.



Here is the article, https://customerfx.com/article/working-with-collections-from-a-web-service-element-in-a-process-in-creatio/

The subprocess method is very poor performance for larger datasets though, and so when we had this problem we ended up having to write C# for it. These aspects need to be improved by Creatio if their desire is to continue to push their platform as being effective at scale with no code solutions.

Hi,

Are you talking about a service created in the configuration or in the "Web services" section?

Dmytro Vovchenko, in the web services section

the question is how to set up its call in c#, so that in the future to use its result in one of the fields of the section

Alexandr Bezbozhnov,

As far as I know, currently, there is no direct way of running this sort of web service from code. However, you can run it inside a business process and you can run this process inside C# code using

ProcessEngineService.svc, with it you even can get the result values of the process.
