### Why is my file not being run?
You're likely getting one of these three import errors:
Could not run file import: Timed out
Could not run file import: Error reading “SSH protocol banner[Errno 104] Connection reset by peer”
Error: ('Connection aborted.', OSError("(104, 'ECONNRESET')"))
**Explanation:**
The connection was closed by another part. This is most likely because the server is overloaded, so you should check the health of your SFTP server.
**Fix:**
Import connection was aborted from the source side - make sure your server can handle the number of open connections and requests it is currently facing, check the connectivity and logs of your source URL.
### Why do I get the 'Field 'ids': Unable to import row: No valid customer id, at least one is required and it should not be longer than 256 bytes. A valid customer id must contain at least one alphanumeric symbol and ids "null" and "undefined" are not allowed. : 3x' error?
**Explanation:**
Data is missing in the import file.
**Fix:**
Check the import file data. Verify whether all 255 lines have some value in the Ids column so that each line can be assigned to some customers.
### Why do I get the Field `timestamp`: This field is required error?
**Explanation:**
Data is missing in the import file. The import file contains an empty property timestamp.
**Fix:**
Check the import file data.
### Why do I get the Could not get a sample from selected file: 1x errror?
**Explanation:**
SFTP connection error means that the server on the client's side dropped the connection for some reason.
**Fix:**
Review your server settings.
### Why do I get the Field `code`: voucher code with this code has been already imported to another pool error?
**Explanation:**
Importing voucher codes are not unique or import files include empty rows.
**Fix:**
Check if your vouchers are unique and if you don't have empty rows at the end of the list.
### Why do I get the Invalid encoding in row error?
**Explanation:**
The errors mean there is an encoding error inside the file/data that you are trying to upload.
**Fix:**
Review the data type and format of the data you are using to upload. The answer/fix is inside the data which at the moment could not be processed.
### Why do I get an error while saving schema definition for a fixed schema import: 1x?
**Explanation:**
The issue happens when the system tries to create a catalog and import items at the same time. The only workaround, for now, is to try the same import a second time. Then the catalog should be already created through the first import, so you can pick it in the UI and then it should work.
**Fix:**
Try to re-import the catalog.
### Why do I get the Field `stock_level`: Field is not a valid number error?
**Explanation:**
The data type in the import setup is incorrect.
**Fix:**
Delete this catalog, create a new one with the same name, and repeat the import. Unfortunately, you cannot change the data type of the column once it is set.
