hi welcome @dhruva1995.
Now we use jpa auto ddl to auto create table when startup first time. If we do not customize the table field type length, the default table field string length is varchar(255), which is not enough for some special fields such as tags, and will cause exception when the field is too long.
So this task is to config the special field string length in @Table file by using java code @Column(length = 2048)
Example Before.

    @Schema(description = "Tags(monitorId:xxx,monitorName:xxx)", example = "{name: key1, value: value1}",
            accessMode = READ_WRITE)
    @Convert(converter = JsonTagListAttributeConverter.class)
    private List<TagItem> tags;

Update:

    @Schema(description = "Tags(monitorId:xxx,monitorName:xxx)", example = "{name: key1, value: value1}",
            accessMode = READ_WRITE)
    @Convert(converter = JsonTagListAttributeConverter.class)
    @Column(length = 2048)
    private List<TagItem> tags;

special table fields: tags, content, template, Param->value
