Signals Notebook: Chemical Drawing element in a experiment is loading indefinitely and crashes the application

When opening an experiment, the chemical drawing element will stay loading indefinitely and the application will crash after a while. The web browser will display warnings about the page being unresponsive.

This issue can happen during copy/paste of a structure or reaction when the values are entered incorrectly, and the raw cdxml data will be added to the stoichiometry table element.

To confirm, please export the experiment to PDF using the API. The resulting pdf of the experiment will contain the cdxml data in the stoichiometry tables.

Solution: Deleting the Chemical Drawing element from the experiment using the API.

IMPORTANT NOTE: This is a procedure that CAN'T be rolled back and has the potential for data loss. Please contact Support if you are not familiar with the below steps*:

1. Obtain the experiments eid by copying it from the URL
2. Navigate to System Configuration > System Settings > API Key
3. Click on 'Open API Document'
4. To identify the ChemDraw element eid:
    4.1. Use GET /entities/{eid}/children (for the eid use the experiment’s id)
    4.2. Copy the id of the ChemDraw element
5. To export a backup of the structure:
    5.1. Use GET/entities/{eid}/export (for the eid use the ChemDraw element’s id and select cdxml in the format)
   5.2. Download the file
6. To delete the ChemDraw element (this operation CAN’T be rolled back):
   6.1. Use DELETE /entities/{eid} (for the eid, use the ChemDraw element’s id and select true in the force dropdrown menu)
