muFunds stopped working (Error Loading ....)

[nicodeceulaer]

It seems the entire fetching from Morningstar has stopped working in the last week.
My google sheet now shows "Error Loading ..." for all invocations of the formula muFunds()

To verify I did not accidently break something in my google sheets, I made a new copy of one of the examples from the muFunds website (https://mufunds.com/usage.html - Examples: Single mutual fund).

The same problem happens in this google sheet document as well.
As an example, this formula now displays "Loading ..." forever:

=VALUE(muFunds("nav", "LU0690375182"))

So I fear Morningstar has changed their HTML format?

I'm having the same issue. Provider: morningstar-fr

Looks like it's working again today.
I am getting wrong values though, but I'll open another issue.

Same here in Portugal, not working since last week. @joseballester Any help from yr side, please.

Not working here in UK. Great addin though so hope sorted soon

[aubreyz]

This works
=VALUE(muFunds("nav", $F50,"morningstar-es"))

This worked before but now fails
=mufunds("nav",C64,"morningstar-gb")

[aubreyz]

This is the error you get in functions that were working perfectly well before

[aubreyz]

I have found that if I change functions that previously worked like
=mufunds("nav",C35,"morningstar-gb")

to just
=mufunds("nav",C35,"morningstar")

They now work again. At the very least this needs documentation

I've started a fork to investigate this problem.

I started by moving the URL's from http:// to https://, thinking this was enough. But it seems the URL just return errors once in a while. Since the entire library is caching the result, it only needs to get the data once from morningstar to keep working.
Regretfully, I started rewriting more and more of the code, so this is not an easy change to take over as a single pull request.
The rewrite was triggered by some error I got in the GAS IDE due to the use of the Xml package (which was deprecated some years ago by google). This triggered me to rewrite the HTML parsing to use Cheerio.
That led to some other changes, including adding some extra functionality (e.g. retrieving other fields of data like AUM of a fund, ...)

Not sure how to proceed now. Due to rewrite I broke some of the countries (I only support DE,NL,BE and UK as those are the ones I typically use)

@nicodeceulaer - I didn't see your comment here, but I also did a bit of a re-write and also used Cheerio to do the parsing of the HTML. It's now been merged in PR #44.
