I had a data dashboard from 5 years or so ago that stopped functioning. I have no idea how long ago this happened as it is seldom used.

Using a slight modification from the sample code in the motionchart documentation (https://developers.google.com/chart/interactive/docs/gallery/motionchart). I have this issue when trying chart.getState() in the console. The html file I used is attached.


Uncaught Error: Error: An invalid exception was thrown.
    at gvjs_0Y.gvjs_.getState (jsapi_compiled_motionchart_module.js:3)
    at <anonymous>:1:7


I have been unable to find any hints online, if anyone can shed insight I would appreciate it. Thanks!

If you can point to your actual web page with the motionchart, we might be able to figure out what is happening.  Just knowing the error is not enough in this case, since this kind of error suggests here is a bug in the library.

That is not possible at the moment, it is hosted only internally. The actual website should not matter if the simple documentation example is producing the same error. As far as I can tell it is a bug in the actual API. Did you look at the file I had attached?

The motionchart is working fine in the documentation page, at least for me.  Going to JSFiddle with the example, it does not work at first for me, using Chrome, because apparently JSFiddle now adds the following to the 'results' iframe:  sandbox="allow-forms allow-scripts allow-same-origin allow-modals allow-popups" which results in this error:

Failed to load 'https://www.gstatic.com/charts/motionchart/1/en/tlz-gviz.swf' as a plugin, because the frame into which the plugin is loading is sandboxed.
If I edit the html in the debugger and remove that sandbox attribute, it works fine.

But this is all an interesting diversion because you are not seeing that error.  

You say you get an exception when you try to execute chart.getState() in the console.  But at what point are you stopped in the debugger?

The only difference I see in your code is that you declared the chart variable globally.  The chart still displays for me, so the question is where are you stopped in the debugger?

The chart displays fine, only the getstate() throws the exception. Thanks for helping me out. Do you see the same exception when calling that method?

I was executing chart.getState() in the debugger console at various times after having created the chart.  That worked fine.   No exceptions.

I also added chart.getState() to the code, after creating the chart, and that also worked fine.  No exceptions.

Which one are you doing?  Give us the specifics so we don't have to guess.

The error you are seeing might only be visible to you, depending on your browser, plugins, and other aspects of the environment.  Flash (used by the motionchart) is increasingly problematic, and I believe it will eventually be completely deprecated, so we could be seeing symptoms of its decline and ultimate death.

Interesting. I'm using chrome Version 62.0.3202.62. Attached is a screenshot of what I see in the javascript console with the chart loaded on the left to make it more clear.

Executing any line of code in the debugger console depends on the context in which it is executing.  That's why I asked where you had stopped execution when you called chart.getState().  If it was back at the global level, after the chart has been drawn, then it might be difficult to say what is happening.  Maybe the page has partially cleaned up things that no longer impact the code, but effectively adding more code via the debugger changes things. If this only happens when you are debugging, I have to ask why does it matter? 

If you want to call chart.getState() within the code, after having drawn the chart, then it ought to work properly at that time.  Have you tried that?  Do console.info(chart.getState()) after your chart.draw() call.

The motionchart is working fine in the documentation page, at least for me.  Going to JSFiddle with the example, it does not work at first for me, using Chrome, because apparently JSFiddle now adds the following to the 'results' iframe:  sandbox="allow-forms allow-scripts allow-same-origin allow-modals allow-popups" which results in this error:

Failed to load 'https://www.gstatic.com/charts/motionchart/1/en/tlz-gviz.swf' as a plugin, because the frame into which the plugin is loading is sandboxed.
If I edit the html in the debugger and remove that sandbox attribute, it works fine.

But this is all an interesting diversion because you are not seeing that error.  

You say you get an exception when you try to execute chart.getState() in the console.  But at what point are you stopped in the debugger?

The only difference I see in your code is that you declared the chart variable globally.  The chart still displays for me, so the question is where are you stopped in the debugger?

That is not possible at the moment, it is hosted only internally. The actual website should not matter if the simple documentation example is producing the same error. As far as I can tell it is a bug in the actual API. Did you look at the file I had attached?

If you can point to your actual web page with the motionchart, we might be able to figure out what is happening.  Just knowing the error is not enough in this case, since this kind of error suggests here is a bug in the library.

I had a data dashboard from 5 years or so ago that stopped functioning. I have no idea how long ago this happened as it is seldom used.

Using a slight modification from the sample code in the motionchart documentation (https://developers.google.com/chart/interactive/docs/gallery/motionchart). I have this issue when trying chart.getState() in the console. The html file I used is attached.


Uncaught Error: Error: An invalid exception was thrown.
    at gvjs_0Y.gvjs_.getState (jsapi_compiled_motionchart_module.js:3)
    at <anonymous>:1:7


I have been unable to find any hints online, if anyone can shed insight I would appreciate it. Thanks!
