Application crashes if model is not available in ollama anymore but has open session

[neilschark]

If I start oterm which has already open sessions for a llama model which is not available anymore, oterm crashes.

Hey thanks! I am currently on a short vacation will fix asap.

No worries, enjoy your vacation, that's more important.

Hey there! Sorry for the delay ;) I looked briefly into this. oterm indeed fails when a model is not present, but does not crash. I will fix this eventually, but would like to land support for a number of other things first. For the time being and as a workaround the obvious thing is to download the model or delete the chat.

Now in your case, it seems that this happens when oterm tries to upgrade the database from an old version of oterm and crashes as it cannot get the default parameters for this model. Could you please verify this is the case? To fix your problem I would suggest deleting the database and start from scratch. To do so, you need to delete the sqlite db found at ~/Library/Application Support/oterm/store.db. Alternatively if you don't want to loose the other conversations you have stored, you can use something like "DB Browser for sqlite" to delete the erroneous chat manually. Please let me know if this helps. I will keep this open and fix it in the near future.

Hello, I hope you had a nice vacation.

Thank you, cleaning up my history indeed works as a workaround!
