Missing exchange rate for certain days

[spearmootz]

we are testing to see if we can use this service. we ran into the following USD->UYU being missing for the following dates.
09-11-2019 -> 10-07-2019. i tried clearing the cache with the v=2019-09-11 and i also tried different sources but most failed except for the default.

any reason why this might be?

i was using the timeseries endpoint to get many quotes at a time. i do find that i have some of the data in the historial rate endpoint

[spearmootz]

the following calls have UYU -> USD but not USD -> UYU which is interesting

var requestURL = 'https://api.exchangerate.host/2019-09-11?base=USD';
var request = new XMLHttpRequest();
request.open('GET', requestURL);
request.responseType = 'json';
request.send();

request.onload = function() {
var response = request.response;
console.log(response);
}

var requestURL = 'https://api.exchangerate.host/2019-09-11?base=UYU';
var request = new XMLHttpRequest();
request.open('GET', requestURL);
request.responseType = 'json';
request.send();

request.onload = function() {
var response = request.response;
console.log(response);
}

so the reason why the base UYU seems to have data is because it in fact returns with a base EUR instead of erroring out

[spearmootz]

on this particular call which is a time series

var requestURL = 'https://api.exchangerate.host/timeseries?start_date=2019-09-11&end_date=2019-09-11&base=UYU';
var request = new XMLHttpRequest();
request.open('GET', requestURL);
request.responseType = 'json';
request.send();

request.onload = function() {
var response = request.response;
console.log(response);
}

the api returns saying the base is UYU, but then the data for that day is in fact in EUR.
