Problem 

When trying to upload images in the OSM campaign's new editor, the following error occurs:
"File extension is not supported."

Explanation

• Social media apps add characters with a period (dot) to the beginning of image file names before uploading them.
• MoEngage interprets any text after a dot as a file extension, which causes the error.

Solution

To fix this error, remove the dot from the file name.

Example

• When additional characters are added at the start of the image file name, it appears as: "Snapinsta.app_431485390_745691364337715_8350453286241390781_n_1080.jpg".
• After removing the dot from the file name, the resulting file must resemble:
  “Snapinstaapp_431485390_745691364337715_8350453286241390781_n_1080.jpg“.
