Error with renv: Header must provide a Content-Length property

Hello,
I am not sure this is the right place to post this, but languageserver is giving me an error when I start VScode on a project with renv activated. This error does not prevent the functioning of the package but it pops out of VScode every time I open a project with renv. I have started to notice this error popping out since the latest update in VScode.

Here's the log of the error. I moved the json configuration that is logged to the attached file for readability.

Thank you

Start by reproducing the reported startup error in VS Code with renv activated, then compare the attached languageserver_error_log.log with the recorded versions and session information. Trace the initialize request and timeout behavior described in the log; done means opening the project no longer produces the “Content-Length” error.
