Hi @Abai,
Because you installed the develop branch,
if you erpnext installed in version 15 then india_compliance must be have in version 15.
bench get-app --branch version-15 https://github.com/resilient-tech/india-compliance.git
If you already installed then please apply the command:
bench switch-to-branch version-15 india_compliance
bench update --patch
Thank You!
