"Invalid requestDate" error

[MAIDubai]

1. I tried the sample code, sending random value to table (by using putTemp()), successfully.
2. I added a function getTemp() in the loop, to read attribute value from the table. I tested it successfully alone (means, without putTemp()).
3. When I am doing both (getTemp() and putTemp()) one after other, getting error, for both function as given below,

Datetime= 201840222113051 Temperature send= 26 ERROR: Invalid requestDate must be in ISO-8601 'basic format'. Got '20184022T211305Z'.

5. Please advise me to solve this issue

Any advice on this? I'm having the same error.
