  This error usually occurs when you are trying to use the toLowerCase() function on a variable that is not a string. Make sure that the variable you are trying to apply the toLowerCase() function to is indeed a string. If it is not, you can convert it to a string using the String() function. For example, if your variable is 'cryptoCode', you can use 'String(cryptoCode).toLowerCase()' to avoid this error. This should fix the 'tolowercase is not a function' error.
