Codedeploy failing randomly at Install not finding appspec.yml

Hi,
I have a Lightsail instance configured to work with CodeDeploy. When I try to deploy I am sometimes getting an error at the Install event saying that the appspec.yml didn't exist. However, sometimes the appspec.yml is not there and some others it is.

Error in CodeDeploy console logs

No such file or directory @ rb_sysopen - /opt/codedeploy-agent/deployment-root/7e9847e4-846e-4609-b85b-c22a3fa0a50d/d-KHM59H4R1/deployment-archive/appspec.yml

The codedeploy-agent logs show the following

The versions are as follows:

codedeploy-agent: 1.6.0-49
OS: Debian GNU/Linux 11 (bullseye)
Ruby: ruby 2.7.4p191 (2021-07-07 revision a21a3b7d23)

Inizia dai log dell’agente CodeDeploy e ispeziona lib/instance_agent/plugins/codedeploy/command_executor.rb intorno alle righe 286-291, in particolare default_app_spec e validate_app_spec_hooks. Riproduci il fallimento intermittente di Install con le versioni indicate Debian 11, Ruby 2.7.4 e agente 1.6.0-49; il lavoro è completato quando viene identificato il motivo per cui appspec.yml è intermittentemente non disponibile e viene aggiunto un fix verificato o una copertura di regressione.
