Error when weaving slides

[michakraus]

I am trying to create some slides using Weave.jl and Remark.jl. When weaving the simple document

# myTitle

## mySubtitle


myAuthor

myDate


---

## Empty Slide

TEST


---

## Hello World


```julia
println("Hello")
```

with

Weave.weave("test.jmd", out_path = "build", doctype  = "github")

I get the error

ERROR: LoadError: MethodError: Cannot `convert` an object of type

When removing any of the three slides, the error disappears.

I am using Julia v1.4.0 and Weave v0.9.4.

Adding an empty julia block

```julia
```

to the beginning of the first slide gets rid of the error, but produces an output file, where

• the second slide is missing
• all slide separators --- are removed:

# myTitle

## mySubtitle


myAuthor

myDate




## Hello World


````julia
println("Hello")
````


````
Hello
````


````
