Hi,

I've started getting the following error across all applications using the charts api.

'Uncaught Error: Must call google.charts.load before google.charts.setOnLoadCallback at Object.google.G.K.T.jl [as setOnLoadCallback] (loader.js:224)'.

This includes a published app (hosted internally) that hasn't been updated for two weeks.

Has there been an update to the api in the last 12 hours that could be causing this?

Thank you.



google.charts.setOnLoadCallback(function () {
    angular.bootstrap(document.body, ['opsRiskApp']);
});

google.charts.load('43', { packages: ['corechart'] });

Yes, this was the planned update of the loader announced last week.  Not enough people tested it, apparently.

This particular error is, I believe, a legitimate error message caused by calling google.charts.setOnLoadCallback before calling google.charts.load.  It is documented that the order should be the other way around.  I hope it will be easy enough for people to fix.

I could make another special check for the case when the first setOnLoadCallback call occurs before the first load call.  I think this is a bad practice, however, which becomes more clear when you consider what happens when there is more than one load call.  Any calls of setOnLoadCallback that occur after the first load call will call the callback immediately after the first load is done, even if the intention is to wait for yet another load call to be done.

So I am curious if there is a legitimate need to call setOnLoadCallback before the first load.  If there is, I might be motivated to add this special check.

Yes I am in the same boat (though a very inexperienced js developer - I simply followed the docs.

All my charts are working fine as I do have setOnLoadCallback after load, except the page that has 2 charts - 1 table and 1 timeline:
 
<script type="text/javascript">
    google.load('visualization', '1.0',{'packages':['timeline', 'table']});
    google.setOnLoadCallback(drawChart);
    google.charts.setOnLoadCallback(drawTable);

This fails as of this morning

Hi Iain,

You appear to be trying to use both the old loader and new loader at the same time.  That is bound to fail since incompatible code will be loaded by each.

So, I would recommend you only use the new loader.  Change your google.load and google.setOnLoadCallback calls to google.charts.load and google.charts.setOnLoadCallback.  See the instructions here:  https://developers.google.com/chart/interactive/docs/basic_load_libs#update-library-loader-code

Many thanks that work now. Thing is it has worked like that wrong way for the last 2 months, but I guess the new release exposed the error.

Like I say I am not a js coder - just s copy-paster

Thanks again
