I believe there may be some problem in dependence on Thymeleaf but this ok no pom.xml

<dependency>

First by convention the files should be placed in the directory: Resources/templates, with the extension . html and it should be noted that all (without exception) the precision tags are closed, and the dependency:

     <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-thymeleaf</artifactId>
    </dependency>

Remembering that the property <version> comes from <parent>. In the controller method the return must be string type and the value must be the file name in the case of "error" without the extension (html) but should not be created in spring-boot, by convecting a controller mapped to the standard error controller.

Mapped "{[/error]}" Mapped "{[/error],produces=[text/html]}"

In case the manager is just not finding the file with the name:

'Resources/templates/error.html'
