Timediff or null time field

Bug reports
1

Hello,

When I have a timediff() on a field that returns null I get an java.lang.NullPointerException error. I found a way to solve it by just adding a contact( timediff () , ‘’) and adding a whitespace will fix the error.

The second issue is related -I would guess - when exploring a table that has a column time and the column has null fields, I am unable to explore it. The visualisation fails with the same error java.lang.NullPointerException

I am using MySQL 8 and latests version of metabase.

Best,
Matias

Hi @mundurraga,

This sounds pretty similar to the issue described here ( https://github.com/metabase/metabase/issues/11665 ), just with a MySQL database. We made some big time-related changes in 0.34 and my guess is this is related. Do you know if this worked OK in a previous version of Metabase?

Thanks,

Damon

There’s actually a really strange issue about timediff() with a few workarounds:
