Please make sure you have not made any typos while adding the API_KEY.

Also, have you enabled your API key? If not, please do so by visiting API section on your Bolt cloud dashboard.

First of all enable your API key from API section on your Bolt cloud dashboard as it is disabled by default.
Carefully enter the API key, especially 0(zero) and O and API key should be enclosed in double inverted commas.
If still not working you can generate a new API key and make sure to update it in your all other projects

Try to enter the correct API key
Check it whether you have entered it correctly or not…
