  <p>I tired with template method again throwing the tslint error.</p>
  <pre><code>const MemberNumber = `MBR${pinCode}${sliceNumber}`
  </code></pre>
  <pre><code> Invalid type &quot;any&quot; of template literal expression  @typescript-eslint/restrict-template-expres
  </code></pre>
  <p>how to fix this.</p>
  <p>Thanks</p>
