"lexical error" using writeManifest() with quarto

i am trying to update a published quarto doc on our posit connect server. when i try to update the manifest using rsconnect::writeManifest() i get the error below.

I specify appDir because my project has 3 published documents, each in their own parent folder. This wasn't an issue initially, but i suspect is now causing the error because the problem text in the error message is contained in a quarto doc in a different folder called make-predictions/.

in my troubleshooting i ran quarto inspect in my terminal and received no error.

Is there anything else I can do to troubleshoot?

i am using quarto 1.6.37, quarto package version ‘1.4.4’ and rsconnect version ‘1.3.1’.

767.25 MB ❯ main ❯ rsconnect::writeManifest(appDir = "monitor-predictions", verbose = TRUE)
Error:

Can you try specifying a vector of files instead of a folder?

Hi!

I've received the same error legend while trying to run rsconnect::writeManifest() in a Quarto dashboard that contains Shiny elements, in order to publish it on Connect Cloud.

The error indicates that there's an "invalid character inside string." and points to a blank space in a character string when there's actually no such space in that named object.

rsconnect::writeManifest()
Error: lexical error: invalid character inside string.
iltered_data$ESCALAFON_OK != ' P.E.P', ]\n# filtered_data_su

The actual piece of code in my .qmd file:

I tried specifying the appMode (quarto-shiny) and the appPrimaryDoc (my .qmd file) but the error persists

Could you say which versions of quarto and R you're using?

5

Yes!

R version 4.1.2
Quarto 1.4.553

Would it be possible for one of you to construct some kind of minimal reproducible example? Perhaps a repo that recreates the structure of the project you're working with?
One possible related issue may be Quarto render error · Issue #7029 · quarto-dev/quarto-cli · GitHub but it's pretty difficult to figure out what's going on from the information you've shared so far.

Yes, I tried with a simpler quarto dashboard with shiny interactivity and i didn't get the same error, but let me show you the logs, as I wasn't able to deploy it neither.

The repo is here GitHub - Datos-SSGRH/test_deploy, and the command i run for the manifest.json was rsconnect::writeManifest(appMode = "quarto-shiny")

In the deploymant phase, it stops in "Installing Dependencies", with this error: 2025-02-24T16:00:04-03:00 e[91mERROR: Validation of YAML cell metadata failed.e[39m

This issue appears only with quarto doc with shiny interactivity. I just changed it to a simple quarto dashboard without shiny and it deployed correctly.
