Hey all,

Our workflows have decided to stop working and looking at the error in LF Forms, I can see the following:

Received an error from the Workflow server during execution of the Workflow service task: "The server encountered an error processing the request. Please see the <a rel="help-page" href="https://*/Forms/api/help">service help page</a> for constructing valid requests to the service. The remote server returned an error: (400) Bad Request. The server encountered an error processing the request. Please see the <a rel="help-page" href="https://*/Forms/api/help">service help page</a> for constructing valid requests to the service. The remote server returned an error: (400) Bad Request. The remote server returned an error: (400) Bad Request.". [LFF5208-WFExecutionError] Details: URL: Error: WFExecutionError Date: 2/10/2023 9:33:45 AM (AUS Eastern Standard Time) HTTP Status Code: 500 Business Process ID: 2 Instance ID: 21330 Business Process Name: Leave Application Request Stack Trace: Caught exception: Laserfiche.Forms.CommonUtils.Exceptions.LFFormsException Message: Received an error from the Workflow server during execution of the Workflow service task: "The server encountered an error processing the request.

[LFF5208-WFExecutionError] at Laserfiche.Forms.Routing.ServiceTask.Execute(Int32 instanceId, IRoutingContext routingContext)

So I went into the Workflow Administration Console to test if the connection to the web service is being made, where I come across the e following error:

The remote server returned an error: (400) Bad Request.

So I went in to check the URL that is having the issue from the first error and I see this page (https://*/Forms/api/help):

Is this right?

When I view the Workflow's counter part (which is on a different machine to Laserfiche Forms), I can see things do appear to seem like they are working 

Inside the folder, C:\Program Files\Laserfiche\Laserfiche Forms\Forms\Api I can only see two files:

- LfFormService.svc and;

- Web.config

Is this right?

This is what is in the Web.config file:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
  <system.web>
    <compilation debug="false" targetFramework="4.0" />
    <customErrors mode="RemoteOnly" />

    </behaviors>
  </system.serviceModel>
  <system.webServer>
    <modules runAllManagedModulesForAllRequests="false" />

</configuration>

Where should I start looking to trying to solve this issue as at this point I am not sure what I can try to do.

Thanks
