TypeError during commit

I see this sometimes and I don't know what causes it:

[Nest] 88   - 08/26/2021, 5:18:21 PM   [HarvesterService] Indexing finished

The error comes when I commit indexing. I see this error in the backend/api logs. The commit seems successful nevertheless.

After merging #185 I have not seen this error during index commit. Closing.
