Scaling moduli this small cannot give you precision in bootstrapping. Here are some other posts explaining this issue. Setting security parameters according to 128 bit security (very small CKKS scaling factor) - #7 by ypolyakov, How to calculate manually Error : Degree [X] must be less than or equal to the correction factor [Y]
By the way, the plaintext modulus has no meaning in CKKS (it is only used in BGV/BFV; the README in the latest version explains the cryptocontext parameters for each scheme). If you want to test code efficiently (rather than full size and security) it is better to keep the ciphertext moduli the full size, but work with a small ring dimension.
