Possible cause for GENERATEJS_TASK error

Are you getting this error message on your Zoho Creator application? If so, do not worry is easy fixable and most of the times its due to the lack of a referenced table data within the Form you are trying to update.

Most of the times the main cause for GENERATEJS_TASK error is caused when we are trying to open a Form using a function that delivers ID parameters to specific fields within the form. You can update a value on a dropdown but you can not reference that parameter to update a field within a subform or other table within the existing Form. You must first fetch the corresponding data before you can update subform fields.

Lets take a look at the below example. Assume you are working with Form A, which has Filed1, Field2 within Form A you have subform Aa & need to update Subfield1 & Subfield2.

Parameters will travel on your url ID & update Form A Fields1 & 2

// First Need to Fetch the corresponding table "On Add/On Load" section of your Form. 

T1 = Table1 [ID == input.Field1]; 

T2 = Table2 [ID == input.Field2]; 

//Now that you have the corresponding data you can update values within a subform.

SubformAa.subfield1 = T1.ID; SubfomrAa.subfield2 = T2.ID;

There are other events that can cause this error to break your app flow. however, this is in my experience the most common one I have seen. Enjoy!!!
