Weird. Looks like you somehow got an not existing emitter type in the database. Did you modify anything using root access?

[ptrcnull]

nope, at most just imported some data from a .csv

[Helium314]

Looks like you imported invalid data. For csv data in the format exported by LocalNlp there is no check done when importing, I think when omitting it I just assumed the imported data is data exported by LocalNlp.

[ptrcnull]

ah! i think i got it:

sqlite> .headers on
sqlite> select * from emitters limit 5;
rfID|rfType|latitude|longitude|radius_ns|radius_ew|note
||55.670509|12.576118|1000.0|1000.0|

not exactly sure how that happened, but i feel like that would be the emitter that's breaking exports

[ptrcnull]

sqlite> delete from emitters where rfType = '';
sqlite> select distinct rfType from emitters;
LTE
WLAN2
WLAN5

that did it, perhaps there could be some safeguard against importing invalid emitters, or filter on exporting whenever they cannot be serialized?

[Helium314]

Yes, it should definitely be added in at least one of those places.
