How ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$” Error Occurs?

Today I get the following error ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$” in python.

How To Solve ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$” Error ?

  1. How To Solve ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$” Error ?

    To Solve ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$” Error I received this error because I had an invisible non-printing character (the BOM, aka Byte Order Mark, aka U+FEFF) at the beginning of an csv file that contained the s3 path.

  2. ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$”

    To Solve ERROR: Bucket name must match the regex “^[a-zA-Z0-9.-_]{1,255}$” Error I received this error because I had an invisible non-printing character (the BOM, aka Byte Order Mark, aka U+FEFF) at the beginning of an csv file that contained the s3 path.

Solution 1

The "Invalid bucket name "thum.images ": Bucket name must match the regex "^[a-zA-Z0-9.\-_]{1,255}$"" error means just what it says: the bucket name must contain some typo or is just wrong as it should meet the following pattern:

  • ^ – start of string
  • [a-zA-Z0-9.\-_]{1,255} – 1 to 255 ASCII letters, digits, dots, - or _ chars
  • $ – end of string.

There can be no whitespaces in the bucket name.

I often get this error because an extra slash gets into the bucket name after I copy/paste the bucket name from the S3 Web page, like aws s3 sync s3:///my-bucket/folder folder, where instead of the triple backslashes there must be just two.

Solution 2

I received this error because I had an invisible non-printing character (the BOM, aka Byte Order Mark, aka U+FEFF) at the beginning of an csv file that contained the s3 path. I was able to find it with this python code:

print(":".join("{:02x}".format(ord(c)) for c in s3_path))

which resulted in feff:… at the beginning of the string which tipped me off. You would expect to see output like 6d:79:2d:70:61:74:68 (i.e. two digit hex numbers).
