Why do you have that? That’s not a valid value for deploy_config (and you probably should be letting Documenter figure out the deploy_config automatically)
Other issues that most likely aren’t directly related to your error:
push!(LOAD_PATH,“…/src/”)
I wouldn’t recommend modifying the LOAD_PATH in your make.jl file. It would be better to replace that with something like
Pkg.develop(path=joinpath(@__DIR__, ".."))
And if you do use LOAD_PATH: is that the right directory to add?
format = Documenter.HTML(prettyurls = false)
I’d recommend the default prettyurls=true, even if that means you have to run a local web server (LiveServer or python -m http.server) to preview your documentation.
