The program crashed because of an invalid insert statement that was generated for table `rDistanceCycling`. The actual problem turned out to be in [sqlite-utils](https://github.com/simonw/sqlite-utils). `Table.insert_all` processes the data to be inserted in chunks of rows and checks for every chunk which columns are used, and it will collect all column names in the variable `all_columns`. The collection of columns is done using a nested list comprehension that is not completely correct. I'm using a Windows machine and had to make a few adjustments to the tests in order to be able to run them because they had a posix dependency. Thanks, kind regards, Frans ``` # this is a (condensed) chunk of data from my Apple healthkit export that caused the problem. # the 3 last items in the chunk have additional keys: metadata_HKMetadataKeySyncVersion and metadata_HKMetadataKeySyncIdentifier chunk = [{'sourceName': 'AppleÂ\xa0Watch van Frans', 'sourceVersion': '7.0.1', 'device': '<<HKDevice: 0x281cf6c70>, name:Apple Watch, manufacturer:Apple Inc., model:Watch, hardware:Watch3,4, software:7.0.1>', 'unit': 'km', 'creationDate': '2020-10-10 12:29:09 +0100', 'startDate': '2020-10-10 12:29:06 +0100', 'endDate': '2020-10-10 12:29:07 +0100', 'value': '0.00518016'}, {'sourceName': 'AppleÂ\xa0Watch van Frans', 'sourceVersion': '7.0.1', 'device': '<<HKDevice: 0x281cf6c70>, name:Apple Watch, manufacturer:Apple Inc., model:Watch, hardware:Watch3,4, software:7.0.1>', 'unit': 'km', 'creationDate': '2020-10-10 12:29:10 +0100', 'startDate': '2020-10-10 12:29:07 +0100', 'endDate': '2020-10-10 12:29:08 +0100', 'value': '0.00544049'}, {'sourceName': 'AppleÂ\xa0Watch van Frans', 'sourceVersion': '6.2.6', 'device': '<<HKDevice: 0x281cf83e0>, name:Apple Watch, manu… | 2021-01-29T20:16:07Z | 2021-02-14T21:04:13Z | 2021-02-14T21:04:13Z | 1cba965a1ddc2bd77db3bc3912aa7e8467e2fa2f | 0 | 929ea7551135df0cc2ac9d67f4fbbecf701a11f6 | 36dc7e3909a44878681c266b90f9be76ac749f2d | NONE | 140912432 | https://github.com/simonw/sqlite-utils/pull/225 |
