[1Ramp Alpha Web App] - Error occurs when post submitted with same title used in previous post (Permlink characters)

Project Information

1. Repository: https://github.com/hapramp/alpha-web
2. Project Name: 1Ramp Alpha Web App
3. Publisher (if applicable): @singhpratyush

Expected behavior

A user should be able to make a post with the same title as a previously created post and the application (1ramp Web) should be able to cater to this and submit the post to the blockchain.

Actual Behaviour

When a user attempts to submit a post with a title that has already been used previously, the application will throw an error. When you create a post with the same title the application prepends the current date & time to the permlink, however, the timestamp is causing an error upon submission to the blockchain via Steem Connect.

Steps to reproduce

1. Go to https://alpha.1ramp.io/feed/

2. Sign in using your Steem Account

3. Using the create the new article option shown within the floating menu, create a post with the title of "This is a title" and the body of "This is the body", select any category and add a tag of "test". Note that the category, body, and tag have no effect on the outcome of these tests.

4. Submit your post to the blockchain.

5. Wait 5 minutes (you can only post every 5 minutes) and then repeat steps 3 & 4.

6. Note that the platform will state that an error has occurred.

Environment

• Browser: Google Chrome (Version 65.0.3325.162 (Official Build) (64-bit))
• Device: MacBook Pro (Retina, 15-inch, Late 2013)
• Operating system: MacOS HighSierra Version 10.13

Issues Details

Upon submitting the first post, the request payload is as follows:

{"operations":[["comment",{"parent_author":"","parent_permlink":"hapramp","author":"votezilla","permlink":"this-is-a-title","title":"this is a title","body":"<p>this is a body</p>\n\n  <div id=\"1ramp-footer\" />\n  <hr>\n  <center>\n  <h4>\n  <a href=\"https://1ramp.io\">\n  <img src=\"https://ipfs.busy.org/ipfs/QmTFN4mf55SRZkP8Ug7jXVP3sXAmH7sd35zMNwLFpgGqNU\"/>\n  </a>\n  <br>\n  See this post on <a href=\"https://play.google.com/store/apps/details?id=com.hapramp\">1Ramp Android</a> and <a href=\"https://alpha.1ramp.io/@votezilla/this-is-a-title\">Web</a>.\n  </h4>\n  </center>","json_metadata":"{\"tags\":[\"hapramp\",\"hapramp-design\",\"design\"],\"app\":\"hapramp/0.0.16\"}"}]]}

This created the following post: https://alpha.1ramp.io/@votezilla/this-is-a-title

When attempting to submit a post with the same title, the following errors are shown within the console:

Error 1

steemconnect.com/api/broadcast:1

Error 2

Within the response from SteemConnect the following error is provided:

{"error":"server_error","error_description":"false: Invalid permlink character: T"}

The following request payload was used in the above request:

{"operations":[["comment",{"parent_author":"","parent_permlink":"hapramp","author":"votezilla","permlink":"20181202T132132047Z-this-is-a-title","title":"this is a title","body":"<p>this is a body</p>\n\n <div id=\"1ramp-footer\" />\n <hr>\n <center>\n <h4>\n <a href=\"https://1ramp.io\">\n <img src=\"https://ipfs.busy.org/ipfs/QmTFN4mf55SRZkP8Ug7jXVP3sXAmH7sd35zMNwLFpgGqNU\"/>\n </a>\n <br>\n See this post on <a href=\"https://play.google.com/store/apps/details?id=com.hapramp\">1Ramp Android</a> and <a href=\"https://alpha.1ramp.io/@votezilla/20181202T132132047Z-this-is-a-title\">Web</a>.\n </h4>\n </center>","json_metadata":"{\"tags\":[\"hapramp\",\"hapramp-design\",\"design\"],\"app\":\"hapramp/0.0.16\"}"}]]}

If you compare the request payload for both of the posts, you can see that when you attempt to create a post that has the same title as a previously created post, a time stamp is being prepended to the permlink. Once the time stamp has been prepended to the permlink, the permlink should then be lowercased using toLowerCase() as currently the error provided relates to one of the uppercase characters within the timestamp.
