We are getting the error in following part of the code:

export function isArrayType(type: ts.Type) {
  return type.symbol.escapedName === 'Array'
}

Adding type.symbol && check will fix the issue.

Fix:

export function isArrayType(type: ts.Type) {
  return type.symbol && type.symbol.escapedName === 'Array'
}
