Server Error in List View

"I have two doctypes: WMC and WM. In WMC, there is a field called “weapon_category,” which is configured as a link field to WM and has been selected as the title field in WCM, as shown in the WCM.png image.

Now, in the WM doctype, when I add the “weapon_category” field to the List Settings, I encounter a server error. However, if I don’t select the “weapon_category” field in the List Settings, there is no error. Also, if I uncheck “SHOW Title In link Field,” then it works fine. However, I need to display it in my list view.

How can I resolve this issue?

@NCP if you could help. this issue arises when the link field document’s naming is set on autoincrement (name field) and title is set the weapon name. I have had similar error.
