Run Migration Script

From any terminal, send an HTTP request. Replace {{rootkey}} with the rootkey from your environment variables, and {{host}} with your FastGPT domain:

curl --location --request POST 'https://{{host}}/api/admin/initv4815' \
--header 'rootkey: {{rootkey}}' \
--header 'Content-Type: application/json'

This resets the scheduled execution fields for apps, removing null values to reduce index size.

From any terminal, send an HTTP request. Replace {{rootkey}} with the rootkey from your environment variables, and {{host}} with your FastGPT domain:

curl --location --request POST 'https://{{host}}/api/admin/init/refreshFreeUser' \
--header 'rootkey: {{rootkey}}' \
--header 'Content-Type: application/json'

This recalculates free-tier user durations. A previous version upgrade did not recalculate time properly, which caused incorrect notifications.
