Teams custom application packages.

New Contributor

Hi Everyone,


Recently I had a issue with uploading a zipped custom application package via teams admin and from installed ms teams.

from user end upload it simply says manifest parsing has failed. and whenever i try from teams admin center it says "can't read the manifest file"

even i tried checking manifest from the Jason validators and for matters. but i couldn't find a solid answer for my issue.


most of the online sources, solution was to add "https://" section in front of your developer website. i tried that but still have the same issue.


when developing the application i followed exactly the same steps mentioned in below GitHub article.




Any idea how to resolve this..?



thank you.
