Dynamics 365 CRM - Retrieve table definitions by name (Optionset) using oData CRM Api v8.2 giving error

[sbpatil1975]

Hi Vagif,

I am using Simple.OData.Client library (version 6.0.1) to fetch OptionSet data from Dynamics 365 api V8.2 using entity metadata id and attribute metatdata id. This approach worked correctly and I was able to retrieve the optionset data without any issue. Only this approach had to make 3 calls (get the metadata id first and then fire query for Optionset)

Another approach that MS suggested to use LogicalName rather MetadataId which would get the result in query as below

api/data/v8.2/EntityDefinitions(LogicalName='entityname')/Attributes(LogicalName='attributename')/Microsoft.Dynamics.CRM.PicklistAttributeMetadata?$select=LogicalName&$expand=OptionSet($select=Options),GlobalOptionSet($select=Options)

reference
https://learn.microsoft.com/en-us/power-apps/developer/data-platform/webapi/retrieve-metadata-name-metadataid#retrieve-definition-items-by-name

This approach gives output exactly same as Metadataid but while parsing the the response from Simple.OData.Client it is giving error

when I debug code at Simple.OData.Client it found that below code is breaking while reading the response

Please let me know how it can fixed, your help really appreciated
