FAQ
When I tried to create a volume, "Error writing field to database (HTTP 400)" was shown and I could not create the volume.
As specification, if "Emoji" or "variant characters" are entered in the description field when you create a volume, it will result in the following error "Error writing field to database (HTTP 400)".
Please retry to create a volume without using "Emoji" or "variant characters" in the description field.
"Variant characters" are the old characters that have the same pronunciation and meaning but different form and shape.
