I’m trying to read a text file in a mapped network drive named Z:. I altered the Ignition.conf file to configure the network drive. When I reviewed the wrapper logs to see if it connected successfully, I saw this so it seems it worked. ```auto INFO | wrapper | 2020/01/14 14:36:44 | Attempting to map the "\\10.10.0.117\upsTagInfo" share to "Z:"... INFO | wrapper | 2020/01/14 14:36:44 | Mapped "Z:". ``` Whenever I run this script to read the file and write it to a tag, it fails ```auto path = '\\\\Z:upsLogs.txt' try: contents = system.file.readFileAsStringpath(path) except: contents = 'failed' system.tag.write('UPS/cushions',contents) ``` ---

Glad you got sorted, and p.s. I forgot to enclose in a code block so the format of my suggested path is also wrong! ---

Hi, I've used the "net use" command on the server and discovered that the syntax should be: V:\Server\Site\_Brooklyn I've updated the conf file, stopped, and started the gateway but to no avail. ---

Uncomment the wrapper debugging line in the config file then start and stop again. Then after the gateway starts back up, check the logs in the gateway webpage under Diagnostics \> Logs. ```auto # Enables Debug output from the Wrapper. wrapper.debug=TRUE ``` ---

Hi, I'm not 100% sure tbh. this the first in the script being called: def Read\_CSV\_File(filePath): rows= listDict= import csv try: with open(filePath,"r") as csvFile: csvData= csv.DictReader(csvFile,header) ``` for row in csvData: listDict.append(row) return listDict except: Error("Failed to read Item Master CSV") ``` ---

The wrapper config maps a drive to Ignition on the gateway. So for it to work the script must be called in a gateway scope ie tag change script, gateway event script... ---

Remove the try except so you can get the backtrace when it fails, which will be in gateway logs. > [@pturmel](#): > > Do you have multiple mappings I think this happens when you map a network drive on the gateway computer as `X:` then map it with ignition using the same `X` letter. I think I've done this myself, but it still works. ---
