JPG-File is suddenly not displayed anymore in OneDrive

Hey guys, 

 

I have a really weird Problem: 
In my Flow im receiving JSON-Data which is then parsed and with the action "Create File in OneDrive for Business" turned into a .jpg Object and uploaded... See the Flow below (only the first part of the whole process):
Flow.PNG

The weird thing now is that this has worked perfectly until this morning and then it suddently stopped. If I now want to open the file it says that "There is no preview for this file that we can show you". I also checked the data which is coming from PowerApps and I see that Flow is still receiving it correctly. I also rebuilt the Flow and reloaded former versions of my PowerApps project but it didn't work.
Another interesting thing I tested is that whenever I gave the image file in PowerApps a bigger size, the size of the uploaded file in OneDrive also increased, which indicates me that the file is not empty, but somehow It cannot be opened or interpreted.
Due to the fact that I made a lot of tests and therefor a lot of uploads in OneDrive for Business I have the assumption that something is blocking this file... I can just repeat that it worked absolutely fine yesterday and now it suddendly stopped working..


I appreciate any kind of help!

Cheers 
Julian

Me neither, but I fixed the problem based on this post: https://powerusers.microsoft.com/t5/Building-Flows/base-64-converting-back-to-image-using-flow-to-se...
Created a .HTML file which includes an image and then converted the file into .JPG. 

Though im still wondering why it didn't work the way I did it... I even put the base64 data which is coming from PowerApps into a decoder and I saw that its the right data which is coming to Flow.
Really weird. 
Thanks for your help though!

Check to make sure you added a .jpg to the Filename in your compose action.  .jpg files that don't have the right extension exhibit the characteristics that you've mentioned.  It could be that something changed in terms of the JSON you are processing so that it no longer includes the file extension in the name.

I checked that, but the filename is correct:
Screen2.PNGScreen3.PNG
For me the weird thing is that I tried it with an older - defenitly working - version of my PowerApps project and it didnt work.
The Flow is still running correctly and as you see data is also received in the right way...

Then I'm not sure why its not working.  I though I would try the obvious one, but if its not that then I suspect you may have to open a support ticket. Especially if it used to work.
