There is a TS typing error when using asText(), asHTML() on a expected rich text field
prismicH.asText(this.\_blogPost.title)
> Argument of type 'any' is not assignable to parameter of type ' | [RTNode, ...RTNode]'.Type 'any' is not assignable to type '[RTNode, ...RTNode]'.Source provides no match for required element at position 0 in target.
The current workaround is to use "as any" to remove the error:
prismicH.asText(this.\_blogPost.title **as any** )

Hello Nicolas,
I'm not sure why you are getting this error. So I'm going to reach out to the team to get more information.

Hello @cptflammin
1. Can you try updating `@prismicio/types` within your project and try again?
2. Can you provide a minimal reproduction?
3. Can you share with us your dependencies version? (package.json)
Thanks,
Priyanka

Hello, thx for reply, feedback, not running better 😕
1. Done: npm install --save-dev @prismicio/types@0.1.25 --color=always

`
"excerpt": [
{
"type": "paragraph",

],
Argument of type 'any' is not assignable to parameter of type ' | [RTNode, ...RTNode]'.Type 'any' is not assignable to type '[RTNode, ...RTNode]'.Source provides no match for required element at position 0 in target.

Hello @cptflammin
Our dedicated team member is not sure about your exact context. You might need to type their "excerpt" property as apparently, and Stencil is typing it as `any[],` which is inaccurate. To do so, you can `import { RichTextField } from "@prismicio/types"` and use this type to type their excerpt prop/property.
But still, It doesn't solve your issue. It would be great to share proper context to troubleshoot it better.
Thanks,
Priyanka
