Sounds like they’re a bit out of their depth.
The build log contains a stack trace which shows that the error is this:
The function HTMLReactParser
checks if the html
argument provided to it is a string
.
When it is not, it throws a TypeError
.
When your build encounters an Error, it will fail and will not deploy.
This is unlikely.
It may be true that you haven’t changed code, but the log clearly references WordPress.
So your site is integrated with a CMS, and an issue like this can easily be caused by a piece of CMS content being structured in a way that the existing site code was not prepared to handle.
Since the stack trace references blog post
I’d start by seeing if anyone has created or edited any blog posts recently.
