Solved the problem using <code>UpdateRecord</code> without adding to upstream <code>ValidateCSV</code>.
In controller services, <code>CSVReader</code> and <code>CSVRecordSetWriter</code> were modified as follows:
<ul>
<li>Changed property <code>Schema Access Strategy</code> of processor <code>CSVReader</code> to <code>User String Fields From Header</code></li>
<li>Changed all properties to the default of processor <code>CSVRecordSetWriter</code></li>
</ul>
 
 
Here are the test results:
<ul>
<li>In <code>GenerateFlowFile</code>, the following text to change to format <code>yyyyMMddHmmss</code> was made into csv
<a href="https://i.stack.imgur.com/Zldok.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Zldok.png" alt="enter image description here" /></a>
</li>
<li>NiFi expressions to be modified in <code>UpdateRecord</code>
<a href="https://i.stack.imgur.com/1hCuT.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/1hCuT.png" alt="enter image description here" /></a>
</li>
<li><code>CSVRecordSetWriter</code> left the default setting and set <code>CSVReader</code> as follows
<a href="https://i.stack.imgur.com/3wjYb.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3wjYb.png" alt="enter image description here" /></a>
</li>
<li>After completing the above setting, the value may be converted without an error
<a href="https://i.stack.imgur.com/oarlt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/oarlt.png" alt="enter image description here" /></a>
</li>
</ul>
 
 
Searched to see the file in the error log and found the cause. It seemed to be inferred as type string, but it was type float, resulting in the above error.
Thank you for your comments. @VikramsinhShinde @Sdairs

Asking a question, there is a problem while sending e-commerce information to BigQuery in a csv file. In csv, the value of the <code>ORDER_DATE</code> column should go into the <code>yyyy-MM-dd HH:mm:ss</code> format in the <code>DATETIME</code> type column in the BigQuery, tried to find some references on Google.
<h3>Environment</h3>
<ul>
<li>Apache NiFi 1.14.0 on Docker</li>
</ul>
<h3>Attempt1</h3>
Replacement Value Strategy was selected to Literal Value, and<code>/ORDER_DATE</code> was added as a new field. The value is as follows:
<pre class="lang-java prettyprint-override"><code>${field.value:toDate('yyyyMMddhhmmss','GMT'):format('yyyy-MM-dd hh:mm:ss', 'GMT')}
</code></pre>
Symptom is below:
<a href="https://i.stack.imgur.com/FirdS.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FirdS.png" alt="enter image description here" /></a>
<h3>Attempt2</h3>
Found a new reference, that the NiFi expression was wrong, so I did another way:
<pre class="lang-java prettyprint-override"><code>${field.value:equals('0'):ifElse('', ${field.value:replace(${field.value},${field.value:toDate('yyyyMMddHHmmss'):format('yyyy-MM-dd HH:mm:ss'):toString()})})}
</code></pre>
Likewise symptom is below:
<a href="https://i.stack.imgur.com/88aGf.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/88aGf.png" alt="enter image description here" /></a>
Someone asked me to open the log, checked and it's as follows:
<blockquote>
java.lang.NumberFormatException: For input string: &quot;2022-01-08 15:22:17&quot;
</blockquote>
Any ideas? Thank you :)

在询问问题时，在csv文件中向BigQuery发送电子商务信息时出现了问题。在csv中，ORDER_DATE列的值应该进入BigQuery中的DATETIME类型列中的yyyy-MM-dd HH:mm:ss格式，试图在BigQuery上找到一些引用。环境Apache NiFi 1.14.0 on Attempt1将替换值策略选择为文字值，并将/ORDER_DATE添加为新字段。其价值如下：${fi
