Google Ads "Missing asset check" error

[dmoz15]

I'm creating HTML5 ads for Google Ads.

I created a new set of ads from copied Adobe Animate files that worked fine themselves when zipped and uploaded to Google Ads. The old ads were published using Adobe Animate 2019. These new ads that do not work were published using Adobe Animate 2020.

These duplicated versions are exactly the same, except for some text changes. I publish them, zip them, and upload to Google, and get the following error:

Make sure the filenames of all files in your .ZIP file are exactly the same as the name listed in the reference file.

For example, if one of the files in your .ZIP file is called path/to/example/asset, but in your HTML file you reference path/to/example/asset2, AdWords will not be able to to find the correct file.

To fix the issue, compare the filename listed above with every file in your HTML5 code. If it is not exactly the same, correct the reference.

More details:
INVALID_URL_REFERENCE: canvas_

Using search/replace, I see the only file with a reference to "canvas_" is the createjs.min.js file in "/libs/1.0.0/".

The old correctly-working published ads contain a "/libs/createjs-2015.11.26.min.js" file instead of the "/1.0.0/createjs.min.js" file. How do I publish my ad with these same settings instead of the"/1.0.0/createjs.min.js" file? That seems to be the problem here.

aqui la solucion

1) Abra libs / 1.0.0 / createjs.min.js
2) Simplemente elimine esta parte: "canvas _"

Disculpa estoy empezando en esto, en que parte encuentro ese lib / 1.0.0 / createjs.min.js

[kenth687@gmail.com]

Pues eso cuando la agregar como libreria interna solo copias la dirección web abres en internet luego la guardas como archivo java y le modificas esa parte

This is the solution:

For me works:
1) Open libs/1.0.0/createjs.min.js in Code editor (Dreamweaver works well)
2) Just delete this part: "canvas_"
Use ctrl+f to find the term.

Ironically enough I fixed this by actually using a linked file that GDN allow, i.e. "https://s0.2mdn.net/ads/studio/cached_libs/createjs_2019.11.15_min.js", you can replace the token so it uses the whitelisted remote file, in your HTML template file replace $CREATEJS_LIBRARY_SCRIPTS  

with

<script src="https://s0.2mdn.net/ads/studio/cached_libs/createjs_2019.11.15_min.js"></script> 

Imagine pushing out a new version of Animate, with a version of createjs that is incompatible with GDN, under what circumstances could that possibly happen? If I was super charitable I would say Google updated their validation, but more likely the sad truth is Adobe just didn't even bother to check after making changes if their product still worked for the way 99% customer use it. I understand the actual bug is in the GDN validation and there isn't a missing linked file, but still for this to be pushed to customers is just terrible.

Thank you very much. This is major fix

Neverthereless, i am very disappointed in the team of Animate 2020. This issue is not good.  Many hours, and many tests later i finally found the sollution by this thread in this community. Many thanx for the starter of the thread, and @andocom for this post. 

I hope Adobe can fix this. Now, for this moment i make a tutorial for myself, so i never have to look for the same problemm. At my blog i will make tutorial for this.

Do you have any bitmap images in your ad?

The fastest way I found to fix this is to include a blank 1x1 PNG on your stage and pack it with the zip.

Hi, I have the same problem.

I fixed them, I cut  a part of line code with substring "canvas_" and banner still working.

I'm programmer and cute substring from code, maybe sometime on one exclusion coul'd be reaction, but code are correct and creation need still working, my working still the same. 

I cute near the substring "canvas_" this '||(b._isCanvas=!0,c=b.src="canvas_"+this._lastTrackedCanvas++)'
