Atlassian Confluence Blueprint wizard - Non existent soy template - confluence

Question

I am building a confluence plugin including blueprint wizard dialog with blueprint. But when I try to load the wizard JS error appears in browser console,
Uncaught error wizard points to a non-existent Soy template, OutputPlugin.Blueprints.Simple.page1Form'. Check your web-resources or server logs.
What I have tried are,
Checked server logs. No evidence was there.
Tried clean and reinstall plugin and SDK.
However, I have already added soy into web resources in atlassian-plugin.xml file.
I followed atlassian confluence plugin tutorial "Write an intermediate blueprint plugin"
I am using Confluence 6.14.0 and atlasisian SDK 8.16.0
atlassian-plugin.xml
<web-resource key="ma2.create_wizard-resources" name="ma2.create_wizard Web Resources">
...
<transformation extension="soy">
<transformer key="soyTransformer">

</functions>
</transformer>
</transformation>
...
<resource type="download" name="outputTemplate.soy.js" location="/soy/outputTemplate.soy" />
</web-resource>
<blueprint key="output-blueprint" content-template-key="output-template" index-key="output-index" i18n-name-key="output.blueprint.name">

</dialog-wizard>
</blueprint>
outputTemplate.soy
{namespace OutputPlugin.Blueprints.Simple}
/**

*/ 
{template .page1Form}
<form action="#" method="post" class="aui">
<fieldset>
<div class="field-group">
<label for="contentvar">{getText('output.blueprint.form.label.title.vName')}</label>
<input id="contentvar" class="text" type="text" name="contentVar">
</div>
</fieldset>
</form>
{/template}

Finally found the solution. First problem was my server console did not logged necessary logs. There were only java jdk and synchrony logs. So I configured logs as mentioned in this confluence support page to have all the logs of "com.atlassian.confluence.core". Then I found the error
[INFO] [talledLocalContainer] com.atlassian.soy.impl.QuieterSoySyntaxException: In file /soy/outputTemplate.soy: End of SoyDoc not at end of line [line 4, column 1].
Finally the problem was a space after end of soy doc.
/**
* A form that accepts a person's name
*/{space}
instead of
/**
* A form that accepts a person's name
*/
