normalizeErrorMessage(message, searchString): boolean

Case-insensitive substring search helper.

Checks if a message contains a search string in a case-insensitive manner. Useful for error pattern matching and string validation.

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

Parameters

Parameter	Type	Description
message	string	The message to search within
searchString	string	The substring to search for

Returns

boolean

True if message contains the search string (case-insensitive)

Examples

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

try {
  // ... operation
} catch (error: unknown) {
  // OLD: error.message.toLowerCase().includes('invalid')
  // NEW:
  if (normalizeErrorMessage(error.message, 'INVALID')) {
    // Handle invalid input error
  }
}
