Re: error in the server's logs

It means that something you sent is not UTF-8.

Check your strings content.

Re: error in the server's logs

Thank you @ab.
Is it possible to check if a string is utf8 or has invalid characters?

Re: error in the server's logs

You have IsValidUtf8() from the mormot.core.unicode.pas unit.

An other error I usually find:

Is this expected due to network conditions?
