D365 - The attribute with AttributeId = 'Guid' was not found in the MetadataCache - MSCRM Solution Export

Error Message during solution export:
The attribute with AttributeId = <GUID> was not found in the MetadataCache.


Root Cause:
A field is deleted from CRM and the field is removed. But the related solution component reference is left behind somehow.


Fix:
Find the component related to the field and remove it.

Note: Make sure to have a back-up of DB or the Org before performing below operations. Need developer level knowledge to perform this!

Step 1: Find the missing component. Get the solutioncomponentid and componenttype by executing the following fetchxml  query after replacing the guid with the attributeid from the error message.

Note: You can XRM toolbox or C# console app to retrieve the record

<fetch top="50" >
  <entity name="solutioncomponent" >
    <all-attributes/>
    <filter type="and" >
      <condition attribute="objectid" operator="eq" value="<GUID>" />
    </filter>
  </entity>
</fetch>

Step 2: Get the "solutioncomponentid" and "componenttype"  from the result of above fetchxml query and use "RemoveSolutionComponentRequest" to remove the component.

var removeComponentReq = new RemoveSolutionComponentRequest()
{
    ComponentId = <GUID - objectid>,
    ComponentType = <int - componenttype>,
    SolutionUniqueName = <string - solution's uniquename>
};

Hope this helps!
