Unexpected character ('B' (code 66)): expected a valid value
You see this error text in Salesforce.
Last updated 11 Oct 2026
What to do
The message starts with Verification Failed and Unexpected character.
It shows when Use Google Search is on and Smarty cannot verify the address. The cause is a change on Google's side: since 2025, Google's search pages need JavaScript, so the app gets no Did You Mean? text. The check writes nothing to the record, and it uses two lookups. TAF is working on a fix.
On the Options tab, untick Use Google Search. Click Save Settings. Verify the record again. An address that Smarty cannot verify then gets Bad or Blank Address.
Applies to
Address Verification 7.3.x. This fix comes from the tested Address Verification implementation guide.
