Hello

The problem is with the binary fields, when odoo convert a dictionary in string with the json.dumps library, and exist a key like frozen dictionary.

For solve this problem.

* Edit the code odoo. (I don't know if it can be override this code in other module).

In the file: 'odoo/odoo/http.py', add the method in the line 1635:

def key_dict2str(self, value):        
	​res = {}        
	​for k, v in value.items():
   	​if isinstance(k, dict):                
	​	​	​k = json.dumps(k, ensure_ascii=False, default=date_utils.json_default) 
            res[k] = v                         
	​	​if isinstance(v, dict):                
	​	​	​res[k] = self.key_dict2str(v)            
	​	​elif isinstance(v, list):                
	​	​	​res_list = []                
	​	​	​for l in v:                    
	​	​	​	​if isinstance(l, dict):
	​	​	​	​	​res_list.append(self.key_dict2str(l))
                 else:                        
	​	​	​	​	​res_list.append(l)                
	​	​	​res[k] = res_list            
	​	​else:                
	​	​	​res[k] = v                        
	​return res

And replace the line:

data = json.dumps(data, ensure_ascii=False, default=date_utils.json_default)

For

data = self.key_dict2str(data)
data = json.dumps(data, ensure_ascii=False, default=date_utils.json_default)

inside the method: def make_json_response(.... in the line 1635.

Hi,

In the account.move model the problem is related to the tax_totals fields, which stores data as frozendict or defaultdict and as the xmlrpc is not able to handle this type of data, it is getting failed.

Until it get fixed in the odoo core, as tweek at the moment, you can specify the list of field names you need to read and get the data. Just exclude the tax_total field from it.

See this answer:  https://www.odoo.com/forum/help-1/can-the-read-operation-fetch-multiple-results-in-the-xml-rpc-api-229678#answer-229679

Thanks

Hi Nathanael Lee,

I also encountered the same problem when I used OdooRPC to access 'account.move' records. It seems that the 'browse' method in the model 'account.move' has some bug. I tried some other ORM methods and they worked fine.

You can check the following example for reference. 

Please Find Example in Comment.

Hope it will be helpful to you.

Dear Jort

Thanks for your detailed answer!

BUT: It seems OdooRPC can not access the account.move model at all. The below code gives me the exactly same error, even though I am only browsing the model for a record. If I do the same with sale.order, it works.

BTW: I am using Odoo V16.

The user has Admin access, so this should not be a problem. Might it be a problem with OdooRPC?

import config
import odoorpc
import os

odoo = odoorpc.ODOO(config.url, 'jsonrpc+ssl', 443)
odoo.login(config.db, config.username, config.password)


AccountMove = odoo.env['account.move']

inv = AccountMove.browse(1465)

The error message is indicating that it's received a frozendict​ object which it's unable to serialize. frozendict​ is a type of immutable dictionary in Python. Try printing the IDs (or any other attribute) of each invoice related to the sale order, rather than trying to print the entire RecordSet. For debugging purposes it might be helpful to add some error-checking code to handle unexpected data types:

for order in SaleOrder.browse(SaleOrder_ids):
    try:
        for invoice in order.invoice_ids:
            print(invoice.id)  # Or any other attribute of the invoice
    except TypeError as e:
        print(f'An error occurred: {e}')
