Hello, I am generating a C# client with NSwag against the Workbench Api swagger.json and when I am posting an action against a contract the returned type is a raw number representing the action id but the swagger.json specifies that a ContractActionOutput with a ContractActionID property is expected so deserialization fails.

Thanks

Workbench UI Take action button is disabled when enum declared in function signature

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

Create a function with the following signature:

enum AnswerType { No, Yes}

function vote(uint questionIndex, AnswerType answer) public {

Configure the function and declare its parameters:

 "Parameters": [
                        {
                            "Name": "questionIndex",
                            "Description": "Question number",
                            "DisplayName": "Question number",
                            "Type": {
                                "Name": "int"
                            }
                        },
                        {
                            "Name": "answer",
                            "Description": "Selected question option",
                            "DisplayName": "Answer to the question",
                            "Type": {
                                "Name": "enum",
                                "EnumValues": ["No", "Yes"]                                
                            }
                        }

Create the application on the Workbench UI app and you won't be able to trigger the Take Action button. All data is correct but the button will remain disabled

Any log messages given by the failure

Expected/desired behavior

When all data types validations are passed on the UI you must be able to trigger the action.

Note: I guess this is a UI related bug as triggering the function throught the REST api works like a charm.

Is the source for Azure blockchain workbench going to be released as opensource?

Just wondering if the source code for the AppServices and/or the worker microservices are going to be released as opensource? It looks like this is just going to be a repository of samples.

There is a lot of blackbox going on behind the scenes which would be nice to see what exactly it's doing.

ServiceBus to Blockchain connection not working (when using existing Blockchain)

When I push a message through the ServiceBus to the Blockchain, the event does not seem to get to the Blockchain - this is only true if instead of creating a new Blockchain (when I create the Workbench resource), I use an existing Blockchain (i.e. I use the Azure template to create a PoA ethereum resource and then associate that endpoint to the Workbench Template). I'm leveraging the latter so I can then use explorer like blk.io to view the blocks, contracts, transactions on the blockchain...

Smart contracts functions with return values

Solidity function returning parameters configuration

Hi, I am looking to the different samples available in this repository and I can't see any json configuration with workflow functions returning parameters

For example:

function myFunction(string param1) public view returns (uint, uint);

Is this scenario not supported yet on Azure Blockchain Workbench?.

If I change the method signature to:

function myFunction(string param1) public;

The error that I am getting in Azure when uploading my contract actually dissapears like the modified signature is what the workbench is looking for, without return parameters.

If this feature is not available yet, is it on the roadmap for the next version?

Thank you very much

I can't retrieve parameters value passed from Logic APP to the activityhub

Hi everyone,

I have an issue with calling smart contract function from logic app.

I am sending a massage to the activityhub from logic app to trigger a function on the contract.

Logic app triggers this function corretly but my issue is that I can't see what parameters the Logic App passed to this function. When I trigger the same function from the API endpoint I am able to see the parameters I passed to the function. Bellow is the message I am sending to the activityhub

{
"ContractActionId": null,
"ConnectionId": @{items('For_each')?['ConnectionId']},
"UserChainIdentifier": "@{items('For_each')?['UserChainIdentifier']}",
"ContractCodeArtifactBlobStorageURL": "@{items('For_each')?['ContractCodeBlobStorageUrl']}",
"OperationName": "CreateContractAction",
"ContractLedgerIdentifier": "@{items('For_each')?['ContractLedgerIdentifier']}",
"WorkflowFunctionName": "@{items('For_each')?['WorkflowFunctionName']}",
"WorkflowName": "@{items('For_each')?['WorkflowName']}",
"ContractActionParameters": [
{
"name": "wifi",

},
{
"name": "radio",
"value": "@{body('Parse_JSON')?['radio']}"
}

],
"RequestId": "@{variables('RequestID')}"

}

PS. I have looked in my SQL database and it looks like these parameters are not getting replicated from the blockchain to the dbo.ContractActionParameter table.

Thanks,
Peter

I have tried several different IP addresses for the node from the consortium. Additionally, lot's of warnings appear when install_blockscout.sh is run. I didn't install any dependencies before running this script, so I may be missing something.

Digital Locker - 2 issues in sol file

There are two issues with the current digitallocker.sol file which caused the contact not to be accepted in workbench:

1. Spelling issue - currently this is how the line looks like in the contract: ContractUpdated("UploadDocments"); the word Documents is misspelt - it should be corrected to ContractUpdated("UploadDocuments");
2. Incorrect contract name - currently this is how the line looks like in the contract: ContractUpdated("AvailableToShare") - it should be corrected to ContractUpdated("ReleaseLockerAccess");

I made the 2 changes in my local copy and was able to execute the application...

Wrong Open Api definition in /api/v1/contracts/{contractId}/actions

This issue is for a: (mark with an x)

- [x] bug report -> please search issues before submitting
- [ ] feature request

Hello, I have generated a C# client for the Azure Workbench Api using Nswag and I am having trouble when calling
/api/v1/contracts/{contractId}/actions endpoint

The swagger.json description specifies that this endpoint returns a type called WorkflowStateTransitionList with a json property called "workflowStateTransitions" but it is actually returning a property called "workflowFunctions" that represents a different type so autogenerated clients can't deserialize the response properly.

Towards the end, it creates a logic app action that gets data from LogicAppGetContractCreationDetails, and suggests setting the userChainIdentifier from that data. However, the stored procedure does not return that bit of data at all.

Also, the screenshot from earlier suggests that the stored proc would take an extra EmailAddress argument, while it only has two:
