Free service for storing logs?

Question

JavaScript

Good afternoon. In the application, some kind of garbage with dates often happens, the customer asked to save the logs somewhere so that you can look at them and understand the problem (the application is on React, it is used in a special shell, so the console is not available there). I tried AWS cloudwatch logs - some kind of garbage with tokens, you can't just take a token, add it to the url and send logs safely. In general, as always, some kind of zapara with this Amazon. Tried the option from sematext (logsene), it doesn't send due to CORS. This is probably due to the fact that the application is on the localhost. So what can you use, so that it is free and without any garbage? Sign up, take a token, and calmly send what you need with it, and then you can see what you need on the site. Is this possible at all?
