Hello everybody, I have a problem with report printing whenever I press the print button to print the contract, it gives me this error  :    

File "/usr/lib/python3.8/mimetypes.py", line 116, in guess_type url = os.fspath(url) TypeError: expected str, bytes or os.PathLike object, not bool

Here is the report.xml file :    

        id="report_contract"
        model="hr.contract"
        string="contract Report"
        name="permanentinitiative.contract_report"
        file="permanentinitiative.contract_report"
        report_type="qweb-pdf"
        attachment="True"
/>

and here is the contract.xml file :  

     
         
             
                 

                     
Report title

                     
This object's name is
                         
                     

                 

             
         
     
 


   
        
            
                
                    

                                                    
                    

                
            
        
    

and here is the models.py and the contract.py in case you want to have an idea about the models:

models.py file :   

class permanentinitiative(models.Model):
    _inherit = 'hr.employee'

contract.py file :   

from odoo import models, fields


class HrContract(models.Model):
    _inherit = "hr.contract"
    term_ids = fields.One2many('hr.contract.type.term', 'contract_type_id')


class HrContractTypeTerm(models.Model):
    _name = 'hr.contract.type.term'
    _description = 'Employee Contract Types Terms'

    contract_type_id = fields.Many2one('hr.contract.type')
    sequence = fields.Integer(default=10)
    name = fields.Char(required=True)
    body = fields.Text(required=True)

I will be grateful if you can help me with this matter and give me hints to solve the problem. Thank you.
