Ver 7.4 tiny string and ESP32 Arduino Flash String Helper

[aaron-neal]

I am updating a project that has been happily on 7.1.0 for a long time now.

Instantly, I was experiencing crashes. After connecting up the debugger I was seeing asserts related to the TinyString work.

In particular this line on the stack:
_object[F("uid")] = uid;

After a little playing around, I have concluded there seems to be an issue with the Flashstring helper macro, F()

changing to _object["uid"] = uid; solved the issue.

Whether I should continue using the F() macro in my projects I don't know, but for the time being everything 3 chars of less has had them removed and I can continue my dev work.

Many thanks for the library.

Hi @aaron-neal,

Thank you very much for reporting this issue!
I just released ArduinoJson 7.4.1 to address it.
Let me know if it works.

Best regards,
