issue in friday-call-demo with redcap_event_name

[aboulang]

For Server info: REDCap 13.8.1 · PHP 7.3.29 (Linux/Unix OS) · MySQL 5.7.34
Running the demo against 2 different REDCap server instances gets the same error:

fields_to_read <- c(
"record_id",
"redcap_event_name",
"sample_collected_date",
paste0("tube_id", 1:tubes_per_collection),
paste0("tube_specimen_type", 1:tubes_per_collection),
paste0("tube_volume", 1:tubes_per_collection)
)

source_project_data <- REDCapR::redcap_read(
redcap_uri = source_credentials$redcap_uri,
token = source_credentials$token,
fields = fields_to_read
)

ERROR: The following values in the parameter "fields" are not valid: 'redcap_event_name'
Error in REDCapR::redcap_read(redcap_uri = source_credentials$redcap_uri, :
The redcap_read() call failed on iteration 1.

Taking the field out allows the read to happen but of course, it is needed for the demo.

I suspect there may be an API change or a change with Will Beasley's REDCapR library
