The behavior of the API when trying to update a document that contains a symbol in a field of type string such as "name": "Product1 14€", will return the error 504 Gateway timeout and will not update the document.

Simulation

1. Make a PUT request to update a document through the API, in the body include the special character in a field of type string.

   { "name": "Product1 14€", ...}2. Look at the API response and verify that it returns the error 504 Gateway timeout.

Workaround

Delete the special character and enter the name of the symbol. For example: "14 euros"
