How to skip a page scrape when table is missing in R - r

Question

I'm building a scrape that pulls the name of a player and the years he played for thousands of different players. I have built an otherwise successful function to do this but unfortunately in some instances the table with the other half of data I need (years played) does not exist. For these instances, I'd like to add a way to tell the scrape to bypass these instances. Here is the code:
(note: the object "url_final" is the list of active webpage URLs of which there are many)
library(rvest)
library(curl)
library(tidyverse)
library(httr)
df <- map_dfr(.x = url_final,
.f = function(x){Sys.sleep(.3); cat(1);
fyr <- read_html(curl(x, handle = curl::new_handle("useragent" = "Mozilla/5.0"))) %>%
html_table() %>%
.[[1]]
fyr <- fyr %>%
select(1) %>%
mutate(name = str_extract(string = x, pattern = "(?<=cbb/players/).*?(?=-\\d\\.html)"))
})
Here is an example of an active page in which you can recreate the scrape by replacing "url_final" as the .x call in map_dfr with:

Here is an example of one of the instances in which there is no table and thus returns an error breaking the loop of the scrape.

How about adding try-Catch which will ignore any errors?
library(tidyverse)
library(rvest)
df <- map_dfr(.x = url_final,
.f = function(x){Sys.sleep(.3); cat(1);
tryCatch({
fyr <- read_html(curl::curl(x,
handle = curl::new_handle("useragent" = "Mozilla/5.0"))) %>%
html_table() %>% .[[1]]
fyr <- fyr %>%
select(1) %>%
mutate(name = str_extract(string = x,
pattern = "(?<=cbb/players/).*?(?=-\\d\\.html)"))
}, error = function(e) message('Skipping url', x))
})
