Recently while trying to invoke the HTTP Request trigger, on passing the token we got the below error from the Postman
{
"error": {
"code": "MisMatchingOAuthClaims",
"message": "One or more claims either missing or does not match with the open authentication access control policy."
}
}
Turned out that we missed the trailing slash for the resource’s value while generating the token.
Recently we observed that our plugin registered on the Delete message of appointment on the PreValidation stage was not getting triggered when we were deleting or updating the occurrence of the Recurring Appointment.
For both of the below operations, our plugin was not getting triggered. The plugin had the logic to delete a few associated records to the appointment record.
Delete operation – This deletes all the existing appointment.
Recurrence Update –This deletes the existing appointment and creates new appointment records based on the new recurrence.
On trying out different things, we saw that the plugin was getting triggered if registered on the PreOperation.
For testing, we registered a sample plugin that throws the InvalidPluginExecutionException and saw it getting triggered in case of PreOpertaion as shown below.
We might get the below error while using LINQ to query Dataverse –
System.NotSupportedException: ‘The method ‘GroupJoin’ cannot follow the method ‘SelectMany’ or is not supported. Try writing the query in terms of supported methods or call the ‘AsEnumerable’ or ‘ToList’ method before calling unsupported methods.’
This error occurs because the GroupJoin method, which is essentially what happens during the into … syntax in LINQ, is not supported in the Dataverse/LINQ provider for Dynamics CRM. The issue is related to how the LINQ provider translates queries into FetchXML or SQL that the Dataverse understands. Specifically, nested joins or SelectMany (used by DefaultIfEmpty() in left joins) are not fully supported by the LINQ provider for Dataverse.
The GroupJoin and DefaultIfEmpty methods (used for left joins) result in queries that cannot be translated directly into FetchXML. The LINQ provider for Dataverse does not support all LINQ-to-Entities features, such as nested joins or advanced grouping logic. When you perform nested joins with DefaultIfEmpty() for left joins, the LINQ provider struggles to translate it into the underlying Dataverse query format, which is why the exception is thrown.
To fix it we can break the query into multiple steps as shown below.
However, here as we are fetching partial data into memory and combining it, it increases transfer and processing overhead and can take a long time to process based on the number of records.
The better alternative from a performance perspective would be to use FetchXML or QueryExpression here.
Recently we had a requirement to make different sets of fields mandatory and non-mandatory on the Quick Create form for Contact, based on the parent record type it is opened from.
Below we have the contact’s quick create form opened from a custom table – custom_contract’s contact lookup.
On using the above properties in our form load script for the quick create form, we can see different sets of fields set as required and recommended on the Quick Create Contact form based on the parent record it is opened from.
In Dataverse, solution dependencies are a vital aspect of managing and deploying applications. Dependencies ensure that required components are present for a solution to work seamlessly across environments. However, with complex solutions, understanding and managing these dependencies can become overwhelming.
The updated dependencies page is designed to simplify dependency management by offering a more intuitive, action-driven experience.
Select a particular component in the solution, right-click>> Advanced >> Show dependencies.
We can see 3 different tabs.
Delete Blocked By (tab): Displays any dependencies preventing deletion of a component. Below we can see that for the Age column, it shows Contact’s System Form as the dependency.
Clicking on the Open option takes us to the component page, where we can see all the forms for the contact table.
Used By (tab): Lists other components dependent on the selected component.
Uses (tab): Shows dependencies that the selected component relies upon.
On clicking Open, it opens the Columns page for that table.
The different actions that we can take are Open and inspect the object, Delete the object, Remove dependency, and open the relevant documentation.
Below we have selected the option Remove dependency. As we saw the dependency here refers to the Contact System form in which we have the age field used.
Select Remove.
We get the success message after the successful removal of the dependency.
i.e. we can see the field removed from the blocking Contact’s System form.
Now if we want we can easily delete that particular field with no object blocking the delete.
Lastly, the Delete option for the solution allows the delete (uninstall) the solution that has dependencies on the solution component.
Using the new features – Create a formula (preview) and Explain this formula we can now easily write, edit, and understand formulas in Power Apps.
To enable it, navigate to switch on – Settings >> Updates >> Preview >> Copilot for formulas
Here in the sample app below, we are trying to set the Items property of the Gallery using Create a formula. Here our gallery control is bound to Cases as the data source.
We can describe what formula we need in plain language.
We can see it generating the formula for us. We have the option to Apply, Discard, and Copy it.
Here we have applied the generated formula.
Another example is where we are setting the Text property.
Here instead of the customer name it considered the Customer Contacted field. So basically we need to review the formula generated.
We can also generate formula from code comments as show below. Simply type the comment and wait for formula to be generated or otherwise press Enter.
The result
Next using Explain this formula we can use the copilot’s ability to explain the formula in plain language.
The result
We can also select specific parts of the formula for explanation.
Below we have selected the Filter keyword and Explain this selection option.
