Please refer attached file.

Not able to replicate your issue here using the 802D Post Processor so I would be guessing that there is a setting wrong in your f3d file, always better if you can upload a file that has the problem.
Meantime attached is a Tapping test example file and the PP used to create the code shown below, hope it is of some help to you 🙂

Probably you are trying to use unsupported tapping cycle..
To be precise are you trying to use tapping with chip breaking? In this case you might get error.
Spot on as usual, forgot about that one 🙂 🙂 🙂

There is the answer for you from @boopathi.sivakumar

Is it supported on your machine ? Does your machine have "Rigid Tap" capability ?
If the machine has the "Rigid Tap" capability then (Without using floating Tap holder) you can simply program the hole more than once at different depths so for example the thread is to be 15mm deep, first tap (84 Cycle) depth goes to -5mm, the machine just completes the cycle then stays at the hole X/Y positions and then does a second cycle but with a 10mm depth, and a third cycle going to the full 15mm depth, this is a recognised method and some machine controls like the HAAS and Fanuc have this capability built in to the control.
I don`t think that your Siemens 802D will have it but it may be an "option" that can be turned on, contact Siemens for this or consult your Siemens Manual.
There are few machines that have the proper chip breaking cycles capability, I used to have a Japanese SUGINO Drill/Tap machine that used a system where I would input the number of the pitch to go in and the number of pitch moves to break the chips, eg M6 x 1.0, program in 3 and back 0.75, depending on material, brilliant machine 🙂 🙂
@boopathi.sivakumar may be able to modify your existing PP to enable the different depth system as in the HAAS but as far as I know it is coded in the control and is called up by the 84 cycle command.
Or maybe the 840D PP will work for you ??
For now all I could find is a modified 840D PP that does output the correct chip breaking code, see below for an example of an M8 x 1.25 tapped hole with chipbreaking.

Anyway, PP file attached and the small Fusion file that I created for the test.
Hope this is of some help and that @boopathi.sivakumar can sort out a PP for you 🙂 🙂

Thanks for the support.
I have tried with the PP you have given.
Still get error. I have attached herewith the error details and the my project.

The best way to try it out is siemens-808d post which supports for tapping with chip breaking cycle. you can post process with that and check whether that works for you or not
Thank you for support.
I understood Siemens 802d do not support Tapping with chip breaking cycle. Hence no problem with Fusion 360 PP.
We tried the program which you have given.
Thanks & Regards
