Common Base44 issues affecting integrations
Platform lock-in makes it expensive to migrate to self-hosted infrastructure
Base44 applications run on Base44's infrastructure with proprietary abstractions. If you need to migrate to AWS, Vercel, or a custom backend, you must substantially rewrite the application since the generated code is tightly coupled to Base44's runtime.
Auto-generated backend API lacks input validation and allows malformed data into the database
Base44's generated REST API endpoints often accept and persist any data that matches the field type without business-rule validation — missing required fields, out-of-range values, or invalid relationships are stored without error.
Limited customization of business logic after the initial app generation
Once Base44 generates the application structure, adding custom business logic that deviates from the generated patterns — complex workflows, conditional processing, third-party integrations — requires working around the platform rather than with it.
NextAuth.js issues we find in Base44 apps
Mixing NextAuth v4 and v5 (Auth.js) patterns
AI tools generate a hybrid of v4 [...nextauth].ts and v5 auth.ts configurations that compile but fail at runtime with cryptic errors.
Session callback not including user ID or role
Generated code uses the default session callback which doesn't include the user's database ID or role, making authorization checks impossible.
JWT strategy used without setting NEXTAUTH_SECRET
AI tools configure JWT sessions but don't set the NEXTAUTH_SECRET environment variable, causing tokens to be signed with an insecure default key.

Frequently asked questions
Can you review my Base44-built NextAuth.js integration?
Yes. We regularly audit NextAuth.js integrations in Base44-built apps. We check for proper error handling, security best practices, and production-ready configuration.
What NextAuth.js issues does Base44 typically create?
Common issues in Base44-generated NextAuth.js code include: mixing nextauth v4 and v5 (auth.js) patterns, session callback not including user id or role, jwt strategy used without setting nextauth_secret. We fix all of these in our code review.
How much does it cost to fix my NextAuth.js integration?
Start with our code audit ($19) to get a complete list of NextAuth.js issues. Most integration fixes are included in our Fix & Ship plan ($199). For complex integrations, we provide a custom quote after the audit.
What NextAuth.js best practices does Base44 typically miss?
AI tools often skip webhook signature verification, proper error handling for API failures, retry logic with exponential backoff, and secure token storage for NextAuth.js. Our review checks all of these and provides specific fixes.
