can we put the try block around just this loadEpidata() line? if the other lines are throwing exceptions, we should handle them in a different way.

I believe this is already the case? The try block is around three lines:
const data = loadEpidata(...)
if (data.datasets.length == 0) {...}
return data;
And the last two can't really error out.

thats what im saying -- the try scope should contain only the line(s) where we anticipate a possible exception
src/api/EpiData.ts
Outdated

can we add more information to this, like the returned status code at the very least? when a user runs into the rate limiting, this will be helpful. in fact, when a 429 is served via the API, it returns this html in the body, which would be even more useful to a user:
<!doctype html>
<html lang=en>
<title>429 Too Many Requests</title>
<h1>Too Many Requests</h1>
<p>Rate limit exceeded for anonymous queries. To remove this limit, register a free API key at https://api.delphi.cmu.edu/epidata/admin/registration_form</p>There was a problem hiding this comment.
Also fixed - it should now include the error code if it's not inside the JSON.

this isnt working for me when it encounters a 429 from making too many requests... it still just says "Failed to fetch API data from API Link."

Still showing no error detail when rate limit has been exceeded: |
Closes #45.
In the Import Dataset dialogue, displays the errors from the EpiData API to the user if one is present:
