Scraping with RSelenium is the best way for this page? --Selenium message:invalid selector

[M_AcostaCH]

** Hi community**

Im want make search in this page and download the Passport data of many PI numbers.

Im try to make the automatic form because are 15.000 PI numbers (dataPI), and all Passport data I need.

Im try with Rselenium but when put click in the Passport selector show me an error:

Selenium message:invalid selector: Compound class names not permitted
  (Session info: chrome=107.0.5304.107)

dataPI <- structure(list(NUMPI = c("PI 092872", "PI 136683", "PI 136692", "PI 136718", "PI 136720", "P 136730")), row.names = c(NA, -6L), class = c("tbl_df", "tbl", "data.frame"))

 ### Escribir el numero PI------------------------------------------
 search_box <- remDr$findElement(using = 'xpath',  '//*[@id="MainContent_txtSearch"]')
 search_box$clickElement()
 search_box$sendKeysToElement(list("PI 092872", key = "enter"))
 
 # click en [link NUM PI] -----------------------------------------------------
 Sys.sleep(1)
 link <- remDr$findElement(using = 'xpath', "//*[@id='passporttab']") # Show error
 link$clickElement()
# In this part im try with other selector, like `css` but is the same error.

*Im not sure that if is possible make this with rvest for make more easy form.

Most large web-facing deliver user-requested results through a paged-Javascript interface that assumes a human clicking on next or equivalent intervention. While it is possible at least in theory to fully automate this, before embarking on that attempt check the source website to see if the data is available through other channels such as ftp or an API.

Is my first time with APIS

I don't know of an R package to search a website to discover if it has an API that's something that has to be done manually. Here's a large collection
