I’m using the Admin API to create a new post using Html instead of MobileDoc format. I’ve verified the endpoint works just fine if I post MobileDoc instead of HTML, but when I try to post HTML by specifying only a few fields like this…

/posts/?source=html

title = "This is a test post using html instead of mobiledoc"
html = "<h1>Test Header</h1><b>Test Body</b>"
status = "draft"

I get a response back like this:

{
	"errors": [{

Guessing you’re running on Node v6 which doesn’t support html -> mobiledoc.

#3

When I run node -v I get v6.16.0.

Ran this and rebooted the server:

sudo npm install -g npm
sudo npm install -g n
sudo n stable

Now I’m on v11.12.0 but I tried the same POST again and got the same error.

Do I have to install the html-to-mobiledoc package separately?

#4

After switching Node versions, you would need to reinstall all dependencies. The easiest way is to delete the node_modules folder and then run npm/yarn again.

Or if you’re using ghost-cli use ghost upgrade --force.

Keep in mind though, that v11 is an unstable, unsupported version of Node. Ghost supports LTS only: https://docs.ghost.org/faq/node-versions/

It is unfortunate that we weren’t able to make html-to-mobiledoc work on Node v6. However, jsdom has already dropped support for Node v6, and as it’s a new feature and only a few weeks before Node v6 is completely EOL, we chose to ship the feature with support in Node v8 and v10 only.

Thanks so much @Hannah! I downgraded Node and forced the upgrade, and it’s working as expected now. :+1:

sudo n 10.15.3
ghost upgrade --force
