I am in the process of migrating a salesforce community from the dev sandbox to full sandbox. I have successfully created and validated all required Components Available in Change Set, (https://help.salesforce.com/articleView?id=changesets_about_components.htm&type=5), except the asset file component. After adding the Asset file component to my change set and uploading, I get the "No managing workspace specified" error when I try to validate and the validation fails. Any pointers on what I might be missing or the correct process to add asset files to change sets and successfully validate and deploy will be highly appreciated.
Thanks, Maumau
