The plugin not working in Docker container

[dpblh]

Hello everyone!
I can't run build of my project in the docker container.
I am seeing a floating bug during the build. Some diagrams are rendered and some fall with an error. This happens completely randomly.

error log

error [object Object] Cannot read property 'replace' of undefined


  TypeError: Cannot read property 'replace' of undefined

I used

docker base image

1. alpine3.10
2. alpine3.13
3. debian:buster
4. ubuntu:18.4

java

1. openjdk8
2. openjdk11
3. openjdk14

node.js

1. node:12
2. node:15

What am I doing wrong?

Hi @dpblh

See https://github.com/baerrach/gatsby-remark-plantuml/blob/master/CONTRIBUTING.md for more details, a summary follows:

Once you have cloned this repository, running npm t will run all the tests.
They should all pass.

You can then run npm v to generate visualisations of the tests which get stored in ./svg/<test-name>.html.
If you open each one of those in a browser they should look correct.

This project is really a pet project I hacked together to get plantuml working with gatsby+remark.

I don't spend any time maintaining it.

If you find a problem and can fix it, then I'll accept pull requests.
