Hello A., and all,

In fact: Currently, on PlantUML, we can not go to a label not previously defined!

Just to avoid the `NPE`, here is a proposal with rearrange the order, as:

@startuml
start

title /api/v1/operations/initializations/{schema}/{table}/batch/{batchUID}

if (Validate payload format) then (Not OK)
    :Set http code = 404 ;

    label sp
    label sp
    label sp
    label sp
    label sp_label1

    :Generate errorCodeUid;
    :Log error with errorCodeUid to Devo;

    stop
else (OK)
    :Search the possible match batch record in DB
    __log possible match__
    - {batchUid} -> batchUid
    ;
    
    If (log record > 0) then (No)
        :Set http code = 403 ;
        'label sp_label0
        goto sp_label1
    else (Yes)
        :Prepare the initial load reponse;
    endif
endif

if (Record filter Provided?) then (Yes)
    :__Filter by__
    - recordFrom
    - recordTo
    ;
else (No)
endif

:Set http code = 200;
:Return Http response;

stop

Sounds like a documentation issue.
