Default serving of page assets not working?

The logs of my apps fill up with errors like these:

anvil.server.NoServerFunctionError: API request routing failed. No @anvil.server.http_endpoint exists with path matching ‘/_’
anvil.server.NoServerFunctionError: API request routing failed. No @anvil.server.http_endpoint exists with path matching ‘/favicon.ico’
anvil.server.NoServerFunctionError: API request routing failed. No @anvil.server.http_endpoint exists with path matching ‘/robots.txt’
anvil.server.NoServerFunctionError: API request routing failed. No @anvil.server.http_endpoint exists with path matching ‘/ads.txt’

What is going on?
Is there some default serving of page assets that Anvil normally handles that is not working?

See here: Really weird server error - #2 by stefano.menci

I get those too, but this is different.

If I open the app in my browser, I get an error in the log (most frequently the ‘/_’) from the session that I started.

The chatGPT reply below suggest that these are standard requests. Since I wasn’t even aware of this and did not change anything, it appears to me that some service that Anvil was providing automatically is not working at the moment?
