I’m running into an issue deploying documentation on GitHub. I have Documenter setup with GitHub actions, and the deployment seems to be running smoothly
```julia
┌ Info: Deployment criteria for deploying devbranch build from GitHub Actions:
│ - ✔ ENV["GITHUB_REPOSITORY"]="markmbaum/ClearSky.jl" occurs in repo="github.com/markmbaum/ClearSky.jl"
│ - ✔ ENV["GITHUB_EVENT_NAME"]="push" is "push"
│ - ✔ ENV["GITHUB_REF"] matches devbranch="main"
│ - ✔ ENV["GITHUB_ACTOR"] exists and is non-empty
│ - ✔ ENV["GITHUB_TOKEN"] exists and is non-empty
└ Deploying: ✔
```
but then it runs into an issue pushing to the documentation branch
```julia
┌ Error: Failed to push:
│ exception =
│ MethodError: no method matching iterate(::Nothing)
```
I’m not sure how to proceed. Could this be an issue with permission? Happy to provide more info if needed.

I have the exact same error happening for [https://github.com/byuflowlab/FLOWFarm.jl](https://github.com/byuflowlab/FLOWFarm.jl) and have not been able to solve the problem. Any insight would be helpful.

Note that unless you tag a stable release, you can only produce a dev docs. I suggest including the following instead of the second line in your README:
```julia
[](https://byuflowlab.github.io/FLOWFarm.jl/dev)
```
Also make sure that the `gh-pages` is selected in your Pages settings in the Github project Settings.

And what’s actually wrong? I can see your docs are there at [https://markmbaum.github.io/ClearSky.jl/dev/](https://markmbaum.github.io/ClearSky.jl/dev/).

You are using [`versions = nothing`](https://github.com/byuflowlab/FLOWFarm.jl/blob/ce9ed64266b0e4bafe9505d651817c4d80d1f796/docs/make.jl#L23) with [Documenter 0.24.3](https://github.com/byuflowlab/FLOWFarm.jl/blob/ce9ed64266b0e4bafe9505d651817c4d80d1f796/docs/Manifest.toml#L44) but that functionality wasn’t available before [Documenter 0.27.3](https://github.com/JuliaDocs/Documenter.jl/blob/v0.27.3/CHANGELOG.md).
