&lt;br /&gt;
Here is showing a list of common errors that a user might encounter while creating a BCO, please see possible solutions below: &lt;br /&gt;
&lt;br /&gt;
#Description Domain: autogenerated step numbers are incorrect or not in sequential order most times. &lt;br /&gt;
#* Solution: Manually change the step numbers starting to 1, 2, 3……&lt;br /&gt;
#Description Domain: manually entered step numbers could be considered as strings during validation, which need to be integers. See the figure below that under '''TREE VIEW JSON''', the '''step_number''' is considered as a string instead of an integer.[[File:Blank diagram(9).png|800px|thumb|center]]&lt;br /&gt;
#* Solution: Go to '''TREE VIEW JSON''', scroll down to '''description_domain''' section. Click on the green text pad icon, and select '''int 1'''. See the figures below.[[File:Blank diagram(8).png|800px|thumb|center]][[File:Blank diagram(7).png|800px|thumb|center]]&lt;br /&gt;
#Description Domain: SHA1_Checksum is not a required field but during validation, empty SHA1_Checksum fields can trigger errors. This error can also happen in I/O domain which has SHA1_Checksum fields.&lt;br /&gt;
#* Solution: Go to '''TREE VIEW JSON''', navigate to the parts that show '''sha1_checksum''', hover the mouse over it, then click on the red cross button that appeared to delete the line. [[File:Blank diagram(10).png|800px|thumb|center]]&lt;br /&gt;
#Execution Domain: '''Environment Variables''' are not highlighted in red but it is mandatory to fill out. &lt;br /&gt;
#* Solution: fill out '''Environment Variables''' as a required field.&lt;br /&gt;
#Error Domain: error message shows up when starting typing in Error Domain.&lt;br /&gt;
#* Solution: the error message won't clear until reaches a proper JSON format so a user needs to a proper JSON format is entered.&lt;/div&gt;</summary>
