    @Kouadio ANDOKOU,

    I believe this has to do with a Data Item of type Password defined in the .bprelease file. If you open the file, in any text editor, and search for initialvalue you should see something like below:

    <actionparameter name="Access Token" expose="true" datatype="32">
      <description><![CDATA[Access Token]]></description>

    Notice the element titled <initialvalue>…</initialvalue>. You want to change its value to:


    The reason for this is the underlying encryption algorithm used by BP changed in v6.6 I believe. So v6.5 doesn't understand the encrypted value of the element since the connector was created in a later version.
