I am having problems with my FTP endpoint. It will work for a little then stop working and give me hostname can't be null. I am using studio version: 3.4.0. My flow is up to the FTP is:
<context:property-placeholder location="environment.properties"/>
<flow name="NpPlaFeedFlow1" doc:name="NpPlaFeedFlow1">
<quartz:inbound-endpoint jobName="GetAttributes" cronExpression="30 * * * * ?" startDelay="500" responseTimeout="10000" doc:name="Quartz" repeatCount="0" repeatInterval="0">
<quartz:event-generator-job/>
</quartz:inbound-endpoint>
<message-properties-transformer doc:name="Message Properties" scope="session">
<add-message-property key="database.server" value="${database.server}"/>
<add-message-property key="database.port" value="${database.port}"/>
<add-message-property key="database.user" value="${database.user}"/>
<add-message-property key="database.password" value="${database.password}"/>
<add-message-property key="database.databaseName" value="${database.databaseName}"/>
<add-message-property key="adwords.promo" value="${adwords.promo}"/>
<add-message-property key="file.fileName" value="${file.fileName}"/>
<add-message-property key="ftp.serverName" value="${ftp.serverName}"/>
</message-properties-transformer>
<component doc:name="Java" class="com.newpig.transformer.GeneratePLA"/>
<file:file-to-string-transformer doc:name="File to String"/>
<logger message="Hostname is: ${ftp.serverName}" level="INFO" doc:name="Logger"/>
<ftp:outbound-endpoint host="${ftp.serverName}" port="21" user="${ftp.user}" password="${ftp.pass}" responseTimeout="10000" doc:name="FTP"/>
When I run the application the logger spits out the correct hostname as you can see below.

Does anyone know what else to check? I have tried replacing host="${ftp.serverName}" with host="cmsdev-steves" and sometimes I can get it to work and sometimes not.
Edit I failed to mention in the original post that I have not been able to get the FTP component to connect at all using the variable. Originally I only had ftp.serverName in my properties file and didn't add it to the message-properties-transformer. I added it to that transformer in hopes that it would pick it up. Again, the logger spits out the right value so I can't see why the FTP endpoint doesn't also get the same value.
