Error from autoname of Access Logs

Problem

Trying to open a private file, I got this error:

Traceback (most recent call last):

• The most recent Access Log had the name AL-00810.
• Autoname for Access Log was defined as “format:AL-{#####}”.
• There was no row like "AL%" in tabSeries.

I wanted to correct the Naming Series but it didn’t show up in the Naming Series Tool.

Workaround

The following two SQL statements fixed the problem for me:

UPDATE `tabDocType` SET autoname = 'AL-.#####' WHERE name = "Access Log";
INSERT INTO tabSeries VALUES ('AL-', 810);
COMMIT;

After this, I did a bench clear-cache && bench restart.

I can show very clearly that when I change Access Log’s autoname to format:AL-{#####} the error comes back again.

Noticed this too. Let’s just drop the naming series fully from logs? It’s not really required.

Removed naming series from access logs. Doesn’t make sense to make logging sequential 😆
