We tried authenticating with the same user and it shows success but still getting above error, don’t know if this was some kind of bug but we tried several time and it was same.

Till the time we know, it was due to reset of password that happened last day. at the end we navigated to data -> connections. 

Which was asking to FIX CONNECTION for the user we were trying to authenticate. Click on FIX CONNECTION or Switch Account and it will fix it instantly

If we are getting below error most probably we are not setting Lookup field correctly

Resource not found for the segment ‘accoutid’

or

Empty segment encountered in request URL. Please make sure that a valid request URL is specified.

Below is the example , how to set Lookup field or customer field in Power automate flow

1. if the field is a simple single lookup field, specify entity  name and GUID
   Example : contacts(GUID)
2. If field is Customer lookup , Specify either account or contact
   Example : accounts(GUID) or contacts(GUID)

We got this error in UCI and not in Legacy WebClient,

1. We were Passing CRM Parameter PrimaryControl to Button in Ribbon workbench

   

2. In JS we were getting FormContext from primaryControl(Executioncontext) which was working fine in the Legacy app
   

   function readXML(primaryControl) {   
   var formContext  = null;
    if (primaryControl!== null) { 
               formContext = primaryControl.getFormContext(); 
            }
       }
   }

3. But when same is called in UCI we get ” ” Script Error, Because here we need to treat primary control as formContext

   

So final change needed in Code is as below

function readXML(primaryControl) {   
var formContext  = null;
 if (primaryControl!== null) {
         if (typeof primaryControl.getAttribute === 'function') {
             formContext = primaryControl; //called from the ribbon.
         } else if (typeof primaryControl.getFormContext === 'function' 
                 && typeof(primaryControl.getFormContext()).getAttribute === 'function') {
            formContext = primaryControl.getFormContext(); // most likely called from the form via a handler
         }
    }
}

Collection was modified; enumeration operation may not execute

Back then at 1st Glance it was not clear what was the error but debugging it pointed the issue,

• Code with the Error:  Error is with ForEach Loop in dictionary object 

EntityCollection nonMandatoryProcessRule = FetchAllProcessRules(organizationService, serviceTypeGUID, categoryTypeGUID, departmentTypeGUID, CustomerTypeBOOL, false , 0);
          
            List<Entity> nonMandatoryProcessRuleLIST = new List<Entity>(nonMandatoryProcessRule.Entities);
          
            foreach (Entity processRuleRecordET in nonMandatoryProcessRuleLIST)
            {
                if (!ValidateProcessRuleConditions.ValidateProcessRuleCondition(processRuleRecordET, currentEntityET , organizationService))
                {
                    try
                    {
                        nonMandatoryProcessRuleLIST.Remove(processRuleRecordET);
                    }
                    catch (Exception ex)
                    {
                        throw new Exception("Error in removing " + processRuleRecordET+"  check  " + ex.Message);
                    }
                }
            }

• Code after Resolving the Error

There are 2 ways we can use it.

1. Using it from Html Resource where we want to use DOM. ( Unsupported not recommended)

parent.document.getElementById("attachmentsGrid").control.refresh();

2. Using Js from an Iframe, use Parent

parent.Xrm.Page.getControl("attachmentsGrid").refresh();

// Form Context (Recommended)

formContext.getControl(“attachmentsGrid”).refresh();

3. Using Js on the Record Itself

Xrm.Page.getControl("attachmentsGrid").refresh();

// Form Context (Recommended)

formContext.getControl("attachmentsGrid").refresh();

We Might be sometime not Seeing above code working, I would recommend debugging it, but the most common issue might be that Code is rendering Before Form is fully loaded.

We can use the below code, to the first check if the context is not null and if null is found return and try after 1 sec that is 1000ms.

Function test(executionContext)
{
//// Get FormContext
formContext = executionContext.getFormContext();
if(formContext  != null)
{
//// Get Grid Control
Var getSubgrid = formContext.getControl("attachmentsGrid");
////If Grid Control is empty , Return and timeout for 1 sec
if(getSubgrid  == null)
{
 setTimeout(function () { test(executionContext); }, 1000);
     return;
}
//// If control is not null refresh the grid
formContext.getControl("attachmentsGrid").refresh();
}

}

• The requirement was to hide create a button on the business process flow on a certain condition and Microsoft document gives a function to use getNavigationBehavior()

Refer : https://docs.microsoft.com/en-us/powerapps/developer/model-driven-apps/clientapi/reference/formcontext-data-process/stage/getnavigationbehavior

• but was getting Error : formContext.data.process.getActiveStage.getNavigationBehavior is not a function
• After some debugging found the Document page code need some amendment

• If this type of issue is identified on page , we have an option to submit feedback and raise It in https://github.com/MicrosoftDocs
