Hii,

Why This Happens:

The field analytic_account_id was removed, renamed, or not defined on account.move.line.

use a safe check in the report template 

edit template and use t-if to check if the filed exists before trying  to print it :

<t t-if="hasattr(line, 'analytic_account_id') and line.analytic_account_id">

    <span t-field="line.analytic_account_id.display_name"/>

</t>

and if the filed is missing or rename so please fix it if you are using  custom module so add that filed 
from odoo import fields, models

class AccountMoveLine(models.Model):

    _inherit = 'account.move.line'

    analytic_account_id = fields.Many2one('account.analytic.account', string='Analytic Account')

 i hope it is use full
