CCL:G: Error: the ESP fitting centers exist, but the fitting value

 Hello,
 I suggest you consider to use Multiwfn code to
 calculate the RESP charges, the procedure is quite easy, and you do not need
 to use any special keyword in the Gaussian calculation. For Gaussian
 users, the .fch or .wfn/.wfx file generated by Gaussian can be directly
 used as input file of Multiwfn for deriving RESP charges. Please check Section
 4.7.7
 of Multiwfn manual, there are a batch of examples.

 Error: the ESP fitting centers exist, but the fitting values are missing
 It is recommened to generate esp file for resp fitting from the gesp file
 generated by adding keyword 'iop(6/50=1) in G09 input'
 I have iop(6/50=1) keyword in the gaussian.
 I used Ambertool 20 and gaussian 09.
 This is problem with gaussian or Antechamber, is there any change i need to
 make in gaussian input?
