Error occurred in deployment step 'Activate Features': Invalid field name

Question

SharePoint Error message Error occurred in deployment step 'Activate Features': Invalid field name.{guid}

Answer 1

Somewhere in your feature you have invalid GUID....check that and make it correct. Use VS create GUID option.

Answer 2

There is an attribute Overwrite for field and content-type definition. Add the attribute and make it true. e.g.

<Field ID="guid"
       Name="---"
       StaticName="---"
       DisplayName="---"
       Type="---"
       Overwrite="True">
</Field>
