Could not launch server runtime - image build failed. (after a pause)

Hi guys, after a break of one month I returned to the application but it no longer works. I get the following errors and i saw that the problem is from python versions/libraries ? I get the error when i call the anvil server.

The error: anvil.server.RuntimeUnavailableError: Could not launch server runtime - image build failed.

When i delete all the packages everything works great but when i add one (pandas, openpyxl anything) i get Status: Error-Build failed last time everything worked great…i didn’t change anything, what can i do? When i’ll finish the app i’ll buy the personal plan but for now with the free plan everything worked great…Thanks guys!



Hi @danniel.tanc,

Custom package installation is only available on paid plans. You are on the Free Plan, which is why the image isn’t building. I’ll raise an issue internally that we should provide a better error message for that. It looks like you used to be on a paid plan, which is why your app used to work with those libraries installed.

If you don’t want to upgrade, then you can always used the Uplink to run any packages that you can’t use in Anvil.
