LoadProhibited-error in Firebase_Signer::handleTaskError() coming from Firebase_ESP_Client::begin() #523

Hello,

with the last changes from 4.3.12 to 4.3.13 I get the following error already when initializing Firebase (still using external client, although at this moment there is not any external client yet assigned):

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

I am not sure what causes this error now (my code theoretically is unchanged since it worked with version 4.3.10). But curiously, when undoing the last change (i.e. deleting the last re-include)

1820 + if (noClient)
1821 +        freeClient(&tcpClient);

in src/signer/Signer.cpp I do not get the latest error mentioned above anymore ... but it returns the error recently reported in #521 ... Looks like that the problem is that tcpClient was deleted before. What I do not understand is why this problem has not occurred already in version 4.3.10.

Best regards, Martin

I don't get any error and the update does the same thing as previously.

You should test with library installation instead of your modification.

mobizt commented 1 year ago

With the same code, there is no error in all tested platforms.

You are right. I said that my code was unchanged, but I missed that accidently, when changing back from my fork to your original library (thank you again for also making optional the use of SD, FS etc., that saves me to include unnecessarily five additional libraries (FS, SPI, SD, SPIFFS, Ethernet) and makes my fork obsolete), the flag USE_LEGACY_TOKEN_ONLY was set, which seems that it has caused my problem. At least it is working now.
