The cause of this issue has been found. That is, the app.json file obtained by my nextcloud instance is incomplete.
I am using a third-party mirror appstore, which using the https://apps.nextcloud.com/api/v1/apps.json as source. Some times, the apps.json is not fullly download to the mirror, and then results to this issue in nextcloud instance.
