postcode_lookup failing unexpectedly about postcodesior HOT 3 CLOSED

Thanks for spotting this issue. I will work on it over the weekend.
Feel free to send a PR if you managed to fix it yourself.

Are you using CRAN or GitHub version?
There are still some changes that haven't been pushed to CRAN so the dev (GitHub) version is the latest.
I don't get the error that you mentioned when running PostcodesioR::postcode_lookup("IM26BG") This line works for me as expected using the dev version.
Was that the only postcode that caused errors? Did you hit the query limit (postcodes.io limits the number of calls)?

In response to your questions:

• I was using CRAN version (0.1.1)
• Yes, it was the only postcode that was throwing an error, out of 257.
• No, I wasn't hitting the query limit, I used map functions from the {purrr} package to iterate over a vector of postcodes one-by-one.

Solution with CRAN version

In case you are interested I solved the problem by using a combination of functions from {purrr} to ignore errors:

# Load libraries
library(tidyverse)
library(PostcodesioR)

# Create vector of postcodes
postcodes <- c("TEST123", "TEST456", "TEST789")

# Geocoding function to check if postcode is valid, and if so, return lat/lng,
# else silently ignore
geocode <- function(postcode){
  if(postcode_validation(postcode)){
    p <- postcode_lookup(postcode)
    tibble(postcode = postcode,
           latitude = purrr::pluck(p, "latitude"),
           longitude = purrr::pluck(p, "longitude"))
  }
}

# Handle errors safely
safe_geo <- safely(geocode)

# Return lat/lng coords
coords <- map(postcodes, safe_geo) %>% 
  transpose() %>% 
  use_series("result") %>% 
  bind_rows()

Dev version

I updated to the GitHub dev version and indeed it no longer throws an error for the same postcode. Thanks for the update 👍
