errorMessageCaseNormalization(message): string

Normalize error message to lowercase for consistent error pattern matching.

Converts error messages to lowercase for case-insensitive substring searching. Useful for matching specific error conditions regardless of message casing.

Consolidated from 8 duplicated patterns in error type matching:

• error.message.toLowerCase().includes('pattern')
• message.toLowerCase().includes('insufficient')

Parameters

Parameter	Type	Description
message	string	The error message to normalize

Returns

string

Lowercase version of the message

Examples

Error pattern matching

import { errorMessageCaseNormalization } from '@gala-chain/launchpad-sdk';

try {
  // ... operation
} catch (error: unknown) {
  const normalized = errorMessageCaseNormalization(error.message);
  if (normalized.includes('insufficient balance')) {
    // Handle insufficient balance
  }
}

Transaction error categorization

import { errorMessageCaseNormalization } from '@gala-chain/launchpad-sdk';

const errorMsg = 'TRANSACTION FAILED: Insufficient Balance';
const normalized = errorMessageCaseNormalization(errorMsg);

if (normalized.includes('insufficient')) {
  console.log('Balance error');
}
if (normalized.includes('transaction')) {
  console.log('Tx error');
}
