Every now and then, I receive an error using Base64Encode. The message is "Please make sure that the encryption dynamic library has already existed." The code is below, offending line in bold. This message does not appear to come from a thrown exception. The reported error line is 16 of this function.

Any ideas what may cause this?

Thanks!

// Convert the current user/password to base64.
STRING    ls_userName, ls_authorizationKey
CODEROBJECT    lnv_coderObject

lnv_coderObject = Create CODEROBJECT

// Avatax-defined key to convert
IF ( f_invalidstr ( as_userName ) ) THEN
    ls_userName = SQLCA.LogID + ':' + cs_prefix + SQLCA.LogPass
ELSE
    ls_userName = as_userName
END IF

// Base 64 encoding
try
    as_authorizationKey = lnv_CoderObject.Base64Encode(Blob(ls_userName,EncodingUTF8!))
catch (Exception se)
    astr_error = f_logError ('Encoding Error', se.getMessage(), '')
end try

RETURN (f_invalidstr(astr_error.message))
