I figured this out - asset triggered dagruns populate `partition_date`
instead of `logical_date`, therefore they return `None` in the template,
causing an error when `strftime` is called on `logical_date`. To fix this I
updated the template to this:
```
log_filename_template = shared/{{ ti.dag_id }}/{%% if ts_nodash or
ti.logical_date %%}{{ ts_nodash |
default(ti.logical_date.strftime("%%Y%%m%%dT%%H%%M%%S")) }}{%% else %%}{%% if
ti.dag_run.partition_date %%}{{
ti.dag_run.partition_date.strftime("%%Y%%m%%dT%%H%%M%%S") }}{%% else
%%}_scheduler{%% endif %%}{%% endif %%}/{{ ti.task_id }}/{%% if ti.map_index >=
0 %%}index_{{ ti.map_index }}/{%% endif %%}attempt_{{ try_number |
default(ti.try_number) }}.log
```
This is quite a cumbersome workaround, do you think it would be possible to
get some kind of consistent ti run identifier between scheduled runs and asset
based runs?
