I’ve not touched the .circleci/config.yml file at any point, and any old previously passing builds are now also failing. I also tried a different image, but nothing works so far.
Go back to your last successful build and get the image ID from the first build step - it is a long 40-character hash (sha256). You can then lock to that hash by using circleci/php:7.2-browsers@(hash).
If that fixes it, then consider that a short-term resolution until you can work out the true cause. It is better if you can avoid locking over the long term, as you won’t benefit from OS security and performance fixes.
Same issue here, also didnt touch the config.yml
Trying the “hack” halfer posted, the correct format is to include “sha-256” before the hash:
circleci/php:7.2-browsers@sha256:hash
