`read_time` with Bard sets throws string conversion error

[mynetx]

The read_time modifier cannot traverse into sets within Bard fields.
Instead, an Array to string conversion error is shown.

Hello!

Has anyone gotten the read_time modifier working with bard when you have sets?

I found this post for awhile ago but its not working for me (post is from V2):
https://statamic.com/forum/2970-read-time-from-bard-fieldtype

When I try this in antlers:

{{ blog_content | flatten | join | strip_tags | read_time:180 }} min read

I get this error:
Error: Array to string conversion

Inside the CMS, at the bottom of the bard field it does show the read time when Im using sets. Not sure if this is helpful but I looked at the source code and its using this package: https://www.npmjs.com/package/read-time-estimate

I also have this problem.
