Hi @urseberry ,
I've made some fixes, but I'm currently encountering an error during the unit tests. Could you help me resolve it?

Here's the error message from the pipeline:

@willianccs Sorry, I'm not able to help. I'm a technical writer, so I'll review the parts of this pull request that impact public documentation, but I don't know how the pipeline or unit tests work. An engineer should review soon, and they will be able to help.

Left a few more wording recommendations.
