Hi,
I recently added a new list to my SharePoint application. I use a lookup to this list from another list. In my devlopment enivorment this works flawlessly. However in production (patched with the new version) it does not work. I get the error: Guid should contain 32 digits with 4 dashes.
I get the same error if I run this request over rest:
"https://{site}.com/sites/{sitname}/{appname}/_api/Web/Lists/GetByTitle('ActivityInstanceList')/Items?$select=ActivityPersonLookup/Name&$expand=ActivityPersonLookup"
The restcall works for development enviorment (reinstalled often from scratch with no data) but gives the error in production (data is retained between all versions).
Does anyone have a clue where to start looking to resolve this issue? Are there some ID missmatches? Do I actually have a GUID field with wrong value? Is it just something I have to edit on the lists running in production ?
Thanks for your time reading this.
