Showing error status("unexpected deal status while waiting for data request: 7") or constantly sealing status while uploading file to filecoin.

[sunnyRK]

Hi, I am facing this issue and I didn't change any code in this.
I am able to run lotus-devnet and ipfs-daemon node. And I can get wallet address and FIL balance. But when I upload file to file coin it showing error status and showing error message like "unexpected deal status while waiting for data request: 7" or sometimes it showing constantly sealing status. It never comes in active status.
I have tried for small file(minimum 1.2kb) and large files as well.
I don't know I am missing something or not. Please help!

Hi, I have trouble in uploading file too. I get this error in console:
Uncaught (in promise) Error: failed to start deal: computing commP failed: generating CommP: getting ipfs block: blockservice: key not found
