This keeps happening in -wmf.13 and -wmf.14: https://logstash.wikimedia.org/goto/f9866a8f6737cbfd5eb32fef328adfd9
It occurs when trying to add a statement for title in LaTeX.

Adding the Math project as it seems that it is properties its datatype that experiences a performance degradation. The cause is still unclear, might very well be in Wikibase.

The error seems to be in the JS when trying to create a new statement with that property. The setClaim api call already contains "type": "unknown", which is incorrect.
claim "{\"type\":\"statement\",\"mainsnak\":{\"snaktype\":\"value\",\"property\":\"P6835\",\"datavalue\":{\"type\":\"unknown\",\"value\":\"Codes+over+$$F_{4}+vF_4$$+F+4+++v+F+4+and+some+DNA+applications\"}},\"id\":\"Q4115189$143dd941-4398-8a1c-f4ac-c82ab03adfd9\",\"rank\":\"normal\"}"That being said, a bad API call should not cause a server error. So we have two problems to fix here.

All of the subtickets have been resolved, no occurrence of this has been recorded in the past three months, safe to assume it's resolved by the subticket.
