analysis.to Analyze SensorData:222 unable to analyze: could not find '*********.find3.ai'

Installed the FIND3 server from source on a raspberry pi 3 running raspbian buster, following the instructions on the official document here: https://www.internalpositioning.com/doc/server_setup.md When running the test suite the analysis fails. Output from AI server is:

I have check at the path given and there is no ***find3.ai file present, there is only an sqlite3.db file. This is the second time I have tried to reinstall the thing from scratch and I encounter the same issue. (Docker installation hanged for a couple of hours, so decided to install it from source)

Running into the same issue. It looks like previously in #89 someone said it just "resolved on its own", so I guess I'll wait a bit. I suspect something's not quite right though...

[Sammy1Am]

An update (on the off-chance @igurvich still cares or anyone comes across this): I installed the find3 app on my phone and did some active learning and it seems to have created the .ai file and now it's happy. Switched back to passive scanning / learning and things are okay.

Seems like probably some sort of issue with passive scanning / learning not initializing the .ai file the same way active does.

Please check your db path permission. We changed our directory permissions to write for our user and then issue solved

[Sammy1Am]

For me, find3 had no issues creating the .ai file when in "active" mode, so the permissions didn't seem to be an issue. It actually looks like passive tracking in general is broken (see #181), and one of the pieces missing is the code to create the .ai file on startup. (Not sure if this is the same situation for OP though)
