Error : Unable to transcode Buffer

Hello, I am trying to get all columns of a table. I did this query :

connexion2
            .query('SELECT top 1 * FROM '+tableName)
            .then(data => {
                
               for(var key in data[0])
                    {
                            console.log(key);
                    }
                
            })
        .catch(error => {
            console.error(error);
        });   

But I get this error :

Uncaught Error: Unable to transcode Buffer [U_INVALID_CHAR_FOUND] at spawn.js :124

I found that it occurs only when I have a Ole object in my table (it works fine with other tables) I don’t want to get the image, I just need the column name. How can I achieve that?

Thank you very much.

Hello For my problem I solved it using .schema(4) instead of query which retrieves the columns names. I’m so sorry aaronbean because I don’t have a solution for this problem. Good Luck…

I’m having this same issue in retrieving a field with BLOB data. I receive this error:

Error: Unable to transcode Buffer [U_INVALID_CHAR_FOUND] at transcode (internal/buffer.js:27:15) at ChildProcess.child.on.exitCode (F:\fst\lxr-converter\node_modules\node-adodb\lib\spawn.js:124:22) at emitTwo (events.js:126:13) at ChildProcess.emit (events.js:214:7) at maybeClose (internal/child_process.js:915:16) at Process.ChildProcess._handle.onexit (internal/child_process.js:209:5)

I’m running Node v8.15.0.

In my case, I really do need this data, as I’m exporting it into another database. Any suggestions? Thanks!
