Thumnail not getting generated

[kota_pardhu]

I've set up ACS on local windows machine and when I access the share application and upload files(.jpg, .png, .doc) to "Shared Files", I dont see thumbnails for the uploaded files, even after refreshing the page after a couple of minutes of upload.

After setting system.thumbnail.generate=true in alfresco-global.properties, thumbnails got generated only for some jpg files(not sure, why it isn't working all the jpg files).

Below are the versions.

ACS => 23.1.0-M4

Share => 23.1.0-M4

alfresco-shared-file-store-controller=> 3.0.0

alfresco-transform-core-aio=> 4.0.0

alfresco-transform-router=> 3.0.0

Below is my alfresco-global.properties

 # Shared File Store properties:

 sfs.endpoint=${sfs.url}/alfresco/api/-default-/private/sfs/versions/1

 # Transform Router properties:
