Upload Issues

Troubleshoot problems uploading contracts to BlockSecOps.


"Upload Failed" Error

Check File Size

Limit: 50MB (500MB for Enterprise)

If your upload is too large:

  • Exclude node_modules/ test files, build artifacts
  • Include only essential dependencies
  • Split into multiple uploads if needed

Check File Format

Supported formats:

  • Individual: .sol, .vy, .rs
  • Archives: .zip, .tar.gz

Not supported: .tar, .rar, .7z

Verify Archive Structure

# Good: Flat or simple structure
project.zip/
├── Token.sol
├── Vault.sol
└── lib/
    └── @openzeppelin/

# Bad: Nested archives
project.zip/
└── another.zip  # Don't nest archives

"Invalid File" Error

Verify Contract Syntax

Compile locally first:

# Foundry
forge build

# Hardhat
npx hardhat compile

If local compilation fails, fix errors before uploading.

Check Pragma Statement

Ensure valid pragma:

// Good
pragma solidity ^0.8.20;
pragma solidity 0.8.20;

// Bad
pragma solidity;  // Missing version

Validate File Encoding

Files must be UTF-8 encoded. Convert if needed:

# Check encoding
file contracts/Token.sol

# Convert to UTF-8
iconv -f ISO-8859-1 -t UTF-8 input.sol > output.sol

"File Not Found" During Scan

Missing Dependencies

Include required dependencies in upload:

Foundry:

zip -r project.zip src/ lib/ foundry.toml remappings.txt

Hardhat:

zip -r project.zip contracts/ node_modules/ hardhat.config.js

Check Import Paths

Verify imports match actual file locations:

// Check this path exists in your upload
import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

Verify Remappings

Foundry - Include remappings.txt:

@openzeppelin/=lib/openzeppelin-contracts/

Or in foundry.toml:

remappings = [
    "@openzeppelin/=lib/openzeppelin-contracts/"
]

Upload Times Out

Large Files

For large uploads:

  1. Use a faster network connection
  2. Try during off-peak hours
  3. Split project into smaller uploads
  4. Contact Enterprise for higher limits

Browser Issues

Try:

  • Different browser
  • Disable extensions
  • Clear cache
  • Check no firewall blocking

API Upload Alternative

Use API for more control:

curl -X POST "https://api.blocksecops.com/api/v1/contracts/upload" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]" \
  --max-time 300

"Permission Denied"

Check Plan Limits

Verify you haven't reached:

  • Monthly scan limit
  • Storage quota
  • Team member limit

Check Organization Access

Ensure you have permission to upload:

  • Must be Member or higher role
  • Must be part of organization
  • Project-level access if applicable

Drag-and-Drop Not Working

Browser Compatibility

Drag-and-drop works best in:

  • Chrome (recommended)
  • Firefox
  • Edge

May not work in:

  • Older Safari versions
  • IE (not supported)

Alternative: File Picker

Click "Browse" or "Select Files" instead of drag-and-drop.


Archive Extraction Errors

Corrupted Archive

Verify archive integrity:

# For zip
unzip -t project.zip

# For tar.gz
tar -tzf project.tar.gz

If corrupted, recreate the archive.

Path Too Long

Windows has 260 character path limit. Solutions:

  • Shorten directory names
  • Move project closer to root
  • Use shorter archive name

Special Characters

Avoid in file/folder names:

  • Spaces (use underscores)
  • Unicode characters
  • Special symbols (!@#$%^&*)

Upload via CLI

If web upload fails, try CLI:

# Install CLI
npm install -g @blocksecops/cli

# Login
blocksecops login

# Upload
blocksecops upload ./contracts

Upload via API

Direct API upload:

# Create archive
zip -r project.zip src/ lib/ foundry.toml

# Upload
curl -X POST "https://api.blocksecops.com/api/v1/contracts/upload" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "[email protected]"

Response:

{
  "id": "contract_abc123",
  "name": "project.zip",
  "files": 15,
  "size": 1048576
}
