panic: runtime error: slice bounds out of range [:18] with capacity 17

[jeffsutherland-bluesky]

I am getting the following error when I use the RandomString transfomer:

panic: runtime error: slice bounds out of range [:18] with capacity 17

My configuration looks like this:

    - schema: "public"
      name: "authentications"
      transformers:
        - name: "RandomString"
          params:
            column: "uid"
            min_length: 7
            max_length: 60

When I comment out that section, the script runs fine. When I include it back, the script fails.

I am using Postgres 12.10-alpine running in Docker on macOS 14.2.1

Can you help me resolve this?

Thank you.

@jeffsutherland-bluesky

Were in your config any other transformers listed in that release note?
https://github.com/GreenmaskIO/greenmask/releases/tag/v0.1.1

If allowed, please attach all the transformers that were applied to the transformed table, it can be just a list of transformers without parameters and column names.

I use the following transformers on that table: * RandomString * RandomEmail * SetNull (x2) From: Vadim Voitenko ***@***.***> Date: Monday, January 29, 2024 at 4:09 PM To: GreenmaskIO/greenmask ***@***.***> Cc: Jefferey Sutherland ***@***.***>, Mention ***@***.***> Subject: Re: [GreenmaskIO/greenmask] panic: runtime error: slice bounds out of range [:18] with capacity 17 (Issue #2) CAUTION: This email originated from outside of the organization.
