• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

I don't understand why github told me that I had to rebase or merge master because branch was out-of-date.

  Didn't run or was cancelled before finishing

^{Note: To save resources, CI tries to finish as soon as an error is found. For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}

The generate() function is getting complex and hard to read. We'll have to look into the issue conan-io/conan#12784 for sure
