[preetjhota]

I am using custom partition table. After flashing it show the following error:
vfs_fat_spiflash: Failed to find FATFS partition (type='data', subtype='fat', partition_label='storage'). Check the partition table

My partition table:

nvs,data,nvs,,0x4000,
otadata,data,ota,,0x2000,
phy_init,data,phy,,0x1000,
storage,data,fat,,0x100000,
ota_0,app,ota_0,,0x150000,
ota_1,app,ota_1,,0x150000,
