Replit displays config errors or your custom run command doesn't execute. The .replit configuration file has syntax errors or missing required fields.
The .replit file controls how your app builds and runs on Replit.
Error Messages You Might See
Invalid .replit configuration
Failed to parse .replit file
run: command not found
Common Causes
- TOML syntax errors (missing quotes, invalid characters)
- Missing 'run' key for deployment command
- Wrong build tool command (e.g., mvn instead of ./gradlew)
- File encoding issues or line endings
- Incorrect module path for multi-module projects
How to Fix It
Validate .replit TOML syntax using a TOML linter. Ensure 'run' command is correct (./gradlew bootRun for Gradle projects). For Spring Boot, use './gradlew bootRun' or java -jar. Set appropriate working directory if needed. Verify file is saved as plain text with Unix line endings.

I’m a Senior Python Developer specializing in building secure, scalable, and highly available systems. I work primarily with Python, Django, FastAPI, Docker, PostgreSQL, and modern AI tooling such as PydanticAI, focusing on clean architecture, strong design principles, and reliable DevOps practices. I enjoy solving complex engineering problems and designing systems that are maintainable, resilient, and built to scale.

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
