this error means that you have a problem in the format of the key constraint so can you please set a correct format to the like
You can try with code like this but please change the name of the table & the columns & the keys

I did as you said but it shows me an error
I want two external keys, not one but two

If you got the same format so the issue is in the other table or the format of the ID in the other table, let's try to change it make it like regular ID
