Squamata18S_summ <- entrez_summary(db = "nuccore", web_history=Squamata18S_search$web_history)

@cdraz44 reported the following error

In addition: Warning message: Esummary includes error message: Too many UIDs in request. Maximum number of UIDs is 500 for JSON format output.

Code worked as of October 26, 2023 when Squamata18S_Search retrieved 498 hits.
Found people on the rentrez github page with the same issue.
Error occurs with entrez_summary function when hits exceed 500. Someone deposited more 18S sequences into genbank between October 26 and today, causing the code to break. Fixed by changing JSON format output to XML format output
