• Platform: Linux 4.15.0-99-generic Ubuntu x86_64 GNU/Linux
• Mercury Parser Version: "@postlight/mercury-parser": "^2.2.0"
• Node Version (if a Node bug):
• Browser Version (if a browser bug):

Expected Behavior

when calling mercury parser either through CLI or node on certain urls it should successfully parse them

Current Behavior

instead the parser simply throws the following exception stack

Same problem

[rothnic]

I ran into this same issue. I have no solution, but I did notice that it was happening when trying to load the next page and running into 400 response for the next page, rather than a 200. I was able to get it to at least not fail completely when using the undocumented fetchAllPages option.

For example:

Mercury.parse(null, { contentType: 'markdown', fetchAllPages: false })
