solana getParsedAccountInfo returns null in value

Solution 1:

Accounts in Solana store lamports (SOL) and data, and in this case, your account only has SOL in it, and no data, which is why the value is coming up as null. For example, the token program at TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA will also show the bytes of the data in the account along with the balance:

$ solana account TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA
Public Key: TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA
Balance: 1.08999168 SOL
Owner: BPFLoader2111111111111111111111111111111111
Executable: true
Rent Epoch: 161
Length: 156480 (0x26340) bytes
0000:   7f 45 4c 46  02 01 01 00  00 00 00 00  00 00 00 00   .ELF............
.... rest omitted for length ....

If you want data inside your account, you must allocate data to it, assign it to a program, and use a transaction on the program to modify the data.
