Hello,
I have started to receive a very similar error: anvil.server.RuntimeUnavailableError: Could not launch server runtime - image build failed.
anvil.server.RuntimeUnavailableError: Could not launch server runtime - image build failed.
My application worked perfectly. I did not update the code, nor did I try to install new packages.
I opened a ticket: The server runtime for your app could not be built
Could it be the same problem?
