I'm deploying the FA1.2 contract with the online LIGO IDE,

Here's a link to the SC: https://ide.ligolang.org/p/QZ85RIfszExxeDPEf_W52A

and i'm initializing the storage this way:

(Pair (Pair {} "tz1djN1zPWUYpanMS1YhKJ2EmFSYs6qjf4bW") 0)

But I got 

Error: ligo: : Parse error in file "", line 0, characters 12-13, after "Pair" and before "{":
      121: <syntax error> {}

Can anyone confirm that i'm initializing the storage the right way? If not, what's the correct format?

Thank you.

    Can you share the command you use to initialize the storage? My guess is that your storage is in Michelson syntax, whereas the command you requires the PascaLIGO syntax, which would be record [ owner = ("tz1djN1zPWUYpanMS1YhKJ2EmFSYs6qjf4bW" : address); totalSupply = 0n; ledger = (big_map [] : big_map (address, account)); ]

  • Thank you for responding. Yes I put the initialization in Michelson format, and changing with your command resolved the issue. Have you any ressource on initialization the storage in PascaLIGO syntax?

Here's the parameter values to initialize storage for the fa1.2 contract. It is working well on my side. If you want to more look at pascaligo syntax, you can visit ligolang doc pages on https://ligolang.org/docs/language-basics/maps-records and https://ligolang.org/docs/tutorials/get-started/tezos-taco-shop-smart-contract/#populating-our-storage-in-a-dry-run

record [owner="tz1djN1zPWUYpanMS1YhKJ2EmFSYs6qjf4bW"; totalSupply=100n; ledger=big_map[("tz1djN1zPWUYpanMS1YhKJ2EmFSYs6qjf4bW" : address)->record[balance=100n; allowances=map[("tz1djN1zPWUYpanMS1YhKJ2EmFSYs6qjf4bW" : address)->50n]]]]

BTW,the FA1.2 contract you used looks different from the one in the latest dev version. please check out this : https://gitlab.com/ligolang/ligo/-/blob/dev/src/test/examples/pascaligo/fa-1.2.ligo I generated the share link with new FA1.2 contract containing parameter values. please take a look at this: https://ide.ligolang.org/p/Oj3jhBNoXrAh14hnGcoh8g
