CommandError: Multiple head revisions are present for given argument 'head'; please specify a specific target revision, '<branchname>@head' to narrow to a specific head, or 'heads' for all heads about langflow HOT 4 CLOSED

To fix the error related to multiple head revisions in Alembic when running Langflow, you need to merge the multiple heads. Here are the steps to resolve this issue:

1. Identify the current heads:

   alembic heads

2. Merge the heads:

   alembic merge <head1> <head2> -m "merge heads"

Replace <head1> and <head2> with the actual revision IDs of the heads you want to merge. This will create a new migration script that merges the multiple heads into a single head, resolving the conflict.

Additionally, ensure that Alembic is properly initialized and configured in your Langflow setup. You can refer to the DatabaseService class in src/backend/base/langflow/services/database/service.py for methods like init_alembic and run_migrations to handle Alembic initialization and migrations ^[1][2].
