Thanks for the heads up! The current snapcraft.yaml contains the following:
environment:
GO111MODULE: on
where YAML somehow interprets that “on” as boolean “true”, leading to the following error:
Issues while validating snapcraft.yaml: The ‘environment/GO111MODULE’ property does not match the required schema: true is not of type ‘number’ or true is not of type ‘string’
Adding quotation marks would solve this particular error. However, I suspect that this yet-to-be-documented environment declaration in snapcraft.yaml is for run-time only, so I’ll probably set GO111MODULE elsewhere in the file. Will try to fix it and report back soon.
