Authentication failed

Hi,
I am using NodeMCU with PN532 NFC NXP Modul V3. Compiling worked without issues. But when I read the tags, I always get the following logs:

[15:07:55][D][pn532:364]: Mifare classic
[15:07:56][E][pn532.mifare_classic:101]: Authentication failed - Block 0x04

[15:08:36][I][ota:117]: Boot seems successful, resetting boot loop counter.

What did I do wrong. Is it the NodeMCU?

Best Regards

FWIW, I also see this error in my logs but the tag is successfully read and my Home Assistant automations run successfully.

Same here, but I would like to get rid of it, can it be just the code for the reader?
